feat: add verified wallet accounts to community requests This commit extends the `CommunityRequestToJoin` with `RevealedAddresses` which represent wallet addresses and signatures provided by the sender, to proof a community owner ownership of those wallet addresses. **Note: This only works with keystore files maanged by status-go** At high level, the follwing happens: 1. User instructs Status to send a request to join to a community. By adding a password hash to the instruction, Status will try to unlock the users keystore and verify each wallet account. 2. For every verified wallet account, a signature is created for the following payload, using each wallet's private key ``` keccak256(chatkey + communityID + requestToJoinID) ``` A map of walletAddress->signature is then attached to the community request to join, which will be sent to the community owner 3. The owner node receives the request, and if the community requires users to hold tokens to become a member, it will check and verify whether the given wallet addresses are indeed owned by the sender. If any signature provided by the request cannot be recovered, the request is immediately declined by the owner. 4. The verified addresses are then added to the owner node's database such that, once the request should be accepted, the addresses can be used to check on chain whether they own the necessary funds to fulfill the community's permissions The checking of required funds is **not** part of this commit. It will be added in a follow-up commit.

feat: introduce messenger APIs to extract discord channels As part of the new Discord <-> Status Community Import functionality, we're adding an API that extracts all discord categories and channels from a previously exported discord export file. These APIs can be used in clients to show the user what categories and channels will be imported later on. There are two APIs: 1. `Messenger.ExtractDiscordCategoriesAndChannels(filesToimport []string) (*MessengerResponse, map[string]*discord.ImportError)` This takes a list of exported discord export (JSON) files (typically one per channel), reads them, and extracts the categories and channels into dedicated data structures (`[]DiscordChannel` and `[]DiscordCategory`) It also returns the oldest message timestamp found in all extracted channels. The API is synchronous and returns the extracted data as a `*MessengerResponse`. This allows to make the API available status-go's RPC interface. The error case is a `map[string]*discord.ImportError` where each key is a file path of a JSON file that we tried to extract data from, and the value a `discord.ImportError` which holds an error message and an error code, allowing for distinguishing between "critical" errors and "non-critical" errors. 2. `Messenger.RequestExtractDiscordCategoriesAndChannels(filesToImport []string)` This is the asynchronous counterpart to `ExtractDiscordCategoriesAndChannels`. The reason this API has been added is because discord servers can have a lot of message and channel data, which causes `ExtractDiscordCategoriesAndChannels` to block the thread for too long, making apps potentially feel like they are stuck. This API runs inside a go routine, eventually calls `ExtractDiscordCategoriesAndChannels`, and then emits a newly introduced `DiscordCategoriesAndChannelsExtractedSignal` that clients can react to. Failure of extraction has to be determined by the `discord.ImportErrors` emitted by the signal. **A note about exported discord history files** We expect users to export their discord histories via the [DiscordChatExporter](https://github.com/Tyrrrz/DiscordChatExporter/wiki/GUI%2C-CLI-and-Formats-explained#exportguild) tool. The tool allows to export the data in different formats, such as JSON, HTML and CSV. We expect users to have their data exported as JSON.

refactor: EventSenders forward RequestToJoin decision to control node This is a bigger change in how community membership requests are handled among admins, token masters, owners, and control nodes. Prior to this commit, all privileged users, also known as `EventSenders`, were able to accept and reject community membership requests and those changes would be applied by all users. This commit changes this behaviour such that: 1. EventSenders can make a decision (accept, reject), but merely forward their decision to the control node, which ultimately has to confirm it 2. EventSenders are no longer removing or adding members to and from communities 3. When an eventsender signaled a decision, the membership request will enter a pending state (acceptedPending or rejectedPending) 4. Once a decision was made by one eventsender, no other eventsender can override that decision This implementation is covered with a bunch of tests: - Ensure that decision made by event sender is shared with other event senders - `testAcceptMemberRequestToJoinResponseSharedWithOtherEventSenders()` - `testRejectMemberRequestToJoinResponseSharedWithOtherEventSenders()` - Ensure memebrship request stays pending, until control node has confirmed decision by event senders - `testAcceptMemberRequestToJoinNotConfirmedByControlNode()` - `testRejectMemberRequestToJoinNotConfirmedByControlNode()` - Ensure that decision made by event sender cannot be overriden by other event senders - `testEventSenderCannotOverrideRequestToJoinState()` These test cases live in three test suites for different event sender types respectively - `OwnerWithoutCommunityKeyCommunityEventsSuite` - `TokenMasterCommunityEventsSuite` - `AdminCommunityEventsSuite` In addition to the changes mentioned above, there's also a smaller changes that ensures membership requests to *not* attached revealed wallet addresses when the requests are sent to event senders (in addition to control nodes). Requests send to a control node will still include revealed addresses as the control node needs them to verify token permissions. This commit does not yet handle the case of event senders attempting to kick and ban members. Similar to accepting and rejecting membership requests, kicking and banning need a new pending state. However, we don't track such state in local databases yet so those two cases will be handled in future commit to not have this commit grow larger.

// don't send revealed addresses to admins
refactor: EventSenders forward RequestToJoin decision to control node This is a bigger change in how community membership requests are handled among admins, token masters, owners, and control nodes. Prior to this commit, all privileged users, also known as `EventSenders`, were able to accept and reject community membership requests and those changes would be applied by all users. This commit changes this behaviour such that: 1. EventSenders can make a decision (accept, reject), but merely forward their decision to the control node, which ultimately has to confirm it 2. EventSenders are no longer removing or adding members to and from communities 3. When an eventsender signaled a decision, the membership request will enter a pending state (acceptedPending or rejectedPending) 4. Once a decision was made by one eventsender, no other eventsender can override that decision This implementation is covered with a bunch of tests: - Ensure that decision made by event sender is shared with other event senders - `testAcceptMemberRequestToJoinResponseSharedWithOtherEventSenders()` - `testRejectMemberRequestToJoinResponseSharedWithOtherEventSenders()` - Ensure memebrship request stays pending, until control node has confirmed decision by event senders - `testAcceptMemberRequestToJoinNotConfirmedByControlNode()` - `testRejectMemberRequestToJoinNotConfirmedByControlNode()` - Ensure that decision made by event sender cannot be overriden by other event senders - `testEventSenderCannotOverrideRequestToJoinState()` These test cases live in three test suites for different event sender types respectively - `OwnerWithoutCommunityKeyCommunityEventsSuite` - `TokenMasterCommunityEventsSuite` - `AdminCommunityEventsSuite` In addition to the changes mentioned above, there's also a smaller changes that ensures membership requests to *not* attached revealed wallet addresses when the requests are sent to event senders (in addition to control nodes). Requests send to a control node will still include revealed addresses as the control node needs them to verify token permissions. This commit does not yet handle the case of event senders attempting to kick and ban members. Similar to accepting and rejecting membership requests, kicking and banning need a new pending state. However, we don't track such state in local databases yet so those two cases will be handled in future commit to not have this commit grow larger.

refactor: EventSenders forward RequestToJoin decision to control node This is a bigger change in how community membership requests are handled among admins, token masters, owners, and control nodes. Prior to this commit, all privileged users, also known as `EventSenders`, were able to accept and reject community membership requests and those changes would be applied by all users. This commit changes this behaviour such that: 1. EventSenders can make a decision (accept, reject), but merely forward their decision to the control node, which ultimately has to confirm it 2. EventSenders are no longer removing or adding members to and from communities 3. When an eventsender signaled a decision, the membership request will enter a pending state (acceptedPending or rejectedPending) 4. Once a decision was made by one eventsender, no other eventsender can override that decision This implementation is covered with a bunch of tests: - Ensure that decision made by event sender is shared with other event senders - `testAcceptMemberRequestToJoinResponseSharedWithOtherEventSenders()` - `testRejectMemberRequestToJoinResponseSharedWithOtherEventSenders()` - Ensure memebrship request stays pending, until control node has confirmed decision by event senders - `testAcceptMemberRequestToJoinNotConfirmedByControlNode()` - `testRejectMemberRequestToJoinNotConfirmedByControlNode()` - Ensure that decision made by event sender cannot be overriden by other event senders - `testEventSenderCannotOverrideRequestToJoinState()` These test cases live in three test suites for different event sender types respectively - `OwnerWithoutCommunityKeyCommunityEventsSuite` - `TokenMasterCommunityEventsSuite` - `AdminCommunityEventsSuite` In addition to the changes mentioned above, there's also a smaller changes that ensures membership requests to *not* attached revealed wallet addresses when the requests are sent to event senders (in addition to control nodes). Requests send to a control node will still include revealed addresses as the control node needs them to verify token permissions. This commit does not yet handle the case of event senders attempting to kick and ban members. Similar to accepting and rejecting membership requests, kicking and banning need a new pending state. However, we don't track such state in local databases yet so those two cases will be handled in future commit to not have this commit grow larger.

refactor: EventSenders forward RequestToJoin decision to control node This is a bigger change in how community membership requests are handled among admins, token masters, owners, and control nodes. Prior to this commit, all privileged users, also known as `EventSenders`, were able to accept and reject community membership requests and those changes would be applied by all users. This commit changes this behaviour such that: 1. EventSenders can make a decision (accept, reject), but merely forward their decision to the control node, which ultimately has to confirm it 2. EventSenders are no longer removing or adding members to and from communities 3. When an eventsender signaled a decision, the membership request will enter a pending state (acceptedPending or rejectedPending) 4. Once a decision was made by one eventsender, no other eventsender can override that decision This implementation is covered with a bunch of tests: - Ensure that decision made by event sender is shared with other event senders - `testAcceptMemberRequestToJoinResponseSharedWithOtherEventSenders()` - `testRejectMemberRequestToJoinResponseSharedWithOtherEventSenders()` - Ensure memebrship request stays pending, until control node has confirmed decision by event senders - `testAcceptMemberRequestToJoinNotConfirmedByControlNode()` - `testRejectMemberRequestToJoinNotConfirmedByControlNode()` - Ensure that decision made by event sender cannot be overriden by other event senders - `testEventSenderCannotOverrideRequestToJoinState()` These test cases live in three test suites for different event sender types respectively - `OwnerWithoutCommunityKeyCommunityEventsSuite` - `TokenMasterCommunityEventsSuite` - `AdminCommunityEventsSuite` In addition to the changes mentioned above, there's also a smaller changes that ensures membership requests to *not* attached revealed wallet addresses when the requests are sent to event senders (in addition to control nodes). Requests send to a control node will still include revealed addresses as the control node needs them to verify token permissions. This commit does not yet handle the case of event senders attempting to kick and ban members. Similar to accepting and rejecting membership requests, kicking and banning need a new pending state. However, we don't track such state in local databases yet so those two cases will be handled in future commit to not have this commit grow larger.

feat: introduce messenger APIs to extract discord channels As part of the new Discord <-> Status Community Import functionality, we're adding an API that extracts all discord categories and channels from a previously exported discord export file. These APIs can be used in clients to show the user what categories and channels will be imported later on. There are two APIs: 1. `Messenger.ExtractDiscordCategoriesAndChannels(filesToimport []string) (*MessengerResponse, map[string]*discord.ImportError)` This takes a list of exported discord export (JSON) files (typically one per channel), reads them, and extracts the categories and channels into dedicated data structures (`[]DiscordChannel` and `[]DiscordCategory`) It also returns the oldest message timestamp found in all extracted channels. The API is synchronous and returns the extracted data as a `*MessengerResponse`. This allows to make the API available status-go's RPC interface. The error case is a `map[string]*discord.ImportError` where each key is a file path of a JSON file that we tried to extract data from, and the value a `discord.ImportError` which holds an error message and an error code, allowing for distinguishing between "critical" errors and "non-critical" errors. 2. `Messenger.RequestExtractDiscordCategoriesAndChannels(filesToImport []string)` This is the asynchronous counterpart to `ExtractDiscordCategoriesAndChannels`. The reason this API has been added is because discord servers can have a lot of message and channel data, which causes `ExtractDiscordCategoriesAndChannels` to block the thread for too long, making apps potentially feel like they are stuck. This API runs inside a go routine, eventually calls `ExtractDiscordCategoriesAndChannels`, and then emits a newly introduced `DiscordCategoriesAndChannelsExtractedSignal` that clients can react to. Failure of extraction has to be determined by the `discord.ImportErrors` emitted by the signal. **A note about exported discord history files** We expect users to export their discord histories via the [DiscordChatExporter](https://github.com/Tyrrrz/DiscordChatExporter/wiki/GUI%2C-CLI-and-Formats-explained#exportguild) tool. The tool allows to export the data in different formats, such as JSON, HTML and CSV. We expect users to have their data exported as JSON. Closes: https://github.com/status-im/status-desktop/issues/6690
