Ivan Belyakov d106b449b6 feat(wallet): move wallet-related tables to a dedicated db.
The only place where appDB is used in wallet is activity,
which refers to `keycards_accounts` table. So a temporary
table `keycards_accounts` is created in wallet db and updated
before each activity query.

Pascal Precht e8bac916ec !refactor: introduce `SaveCommunityToken()` and change `AddCommunityToken()`
**This is a breaking change!**

Prior to this commit we had `AddCommunityToken(token *communities,
croppedImage CroppedImage)` that we used to

1. add a `CommunityToken` to the user's database and
2. to create a `CommunityTokenMetadata` from it which is then added to
   the community's `CommunityDescription` and published to its members

However, I've then discovered that we need to separate these two things,
such that we can deploy a community token, then add it to the database
only for tracking purposes, **then** add it to the community description
(and propagate to members) once we know that the deploy tx indeed went
through.

To implement this, this commit introduces a new API
`SaveCommunityToken(token *communities.CommunityToken, croppedImage
CroppedImage)` which adds the token to the database only and doesn't
touch the community description.

The `AddCommunityToken` API is then changed that it's exclusively used
for adding an already saved `CommunityToken` to the community
description so it can be published to members. Hence, the signature is
now `AddCommunityToken(communityID string, chainID int, address
string)`, which makes this a breaking change.

Clients that used `AddCommunityToken()` before now need to ensure that
they first call `SaveCommunityToken()` as `AddCommunityToken()` will
fail otherwise.

Sale Djenic 61527f8c78 chore: synchronization improvements applied to keypairs/accounts
This is the first step of improvements over keypairs/keycards/accounts.
- `SyncKeypairFull` protobuf removed
- `SyncKeypair` protobuf is used for syncing all but the watch only accounts
- `SyncAccount` is used only for syncing watch only accounts
- related keycards are synced together with a keypair
- on any keypair change (either it's just a keypair name or any change made over an
account which belongs to that keypair) entire keypair is synced including related keycards
- on any watch only account related change, that account is synced with all its details

Pascal Precht 4305147f7a feat: add cropping support for community token assets

path provided by `CommunityToken`, to calculate the actual base64
encoded image.

Pascal Precht b8b402da8d feat: store check channel permission responses
This commit adds new tables to the database and APIs in `Messenger` and
communities `Manager` to store `CheckChannelPermissionsResponse`s.

The responses are stored whenever channel permissions have been checked.

The reason we're doing this is so that clients can retrieve the last
known channel permission state before waiting for onchain checks to
finish.

Pascal Precht bf64f97d5a feat: introduce `CheckAllCommunityChannelsPermissions()` API
This API is used to get a permission status of all channels of a given
community.

Clients can use this API to get the provided information for all
community channels with a single RPC call instead of doing one call
for each channel separately.

Pascal Precht 7938297606 feat: introduce `CheckChannelPermissions` API
Similar to `CheckPermissionToJoin()` we now get
a `CheckChannelPermissions()` API.

It will rely on the same `PermissionResponse` types, but gives
information about both `ViewOnlyPermissions` and
`ViewAndPostPermissions`.

Stefan 5b6f7226bb feat(wallet) extract json blobs and add custom migration support
Extended the migration process with a generic way of applying custom
migration code on top of the SQL files. The implementation provides
a safer way to run GO code along with the SQL migrations and possibility
of rolling back the changes in case of failure to keep the database
consistent.
This custom GO migration is needed to extract the status from
the JSON blob receipt and store it in transfers table.

Other changes:
- Add NULL DB value tracking to JSONBlob helper
- Index status column on transfers table
- Remove unnecessary panic calls
- Move log_parser to wallet's common package and use to extract token
  identity from the logs

Notes:
- there is already an index on transfers table, sqlite creates one for
  each unique constraint therefore add only status to a new index
- the planned refactoring and improvements to the database have been
  postponed due to time constraints. Got the time to migrate the data
  though, extracting it can be done later for a more efficient
  implementation

Fix chats reseting when a Sync signal comes for communities (#3539)
* fix(community): stop re-joining comm when receiving a sync community msg

Fixes an issue with chats being reset. Since joining a community resaves the chats with the synced default value, it resets the sate of the chats, losing the unread messages, the muted state and more.
The solution is to block the re-joining of the community. In the case of the sync, we catch that error and just continue on.

* fix(import): fix HandleImport not saving the chat

Doesn't change much, but it could have caused issues in the future, so since we might have modified the chat, we make sure to save them
Also adds a test

* fix tests

Andrea Maria Piana 6acb34bab7 Allow setting up wallet with new config
This commit does a few things:

1) Extend create/import account endpoint to get wallet config, some of
   which has been moved to the backend
2) Set up a loop for retrieving balances every 10 minutes, caching the
   balances
3) Return information about which checks are not passing when trying to
   join a token gated community
4) Add tests to the token gated communities
5) Fixes an issue with addresses not matching when checking for
   permissions

The move to the wallet as a background task is not yet complete, I need
to publish a signal, and most likely I will disable it before merging
for now, as it's currently not used by desktop/mobile, but the PR was
  getting to big

URL unfurling (initial implementation) (#3471)
This is the initial implementation for the new URL unfurling requirements. The
most important one is that only the message sender will pay the privacy cost for
unfurling and extracting metadata from websites. Once the message is sent, the
unfurled data will be stored at the protocol level and receivers will just
profit and happily decode the metadata to render it.

Further development of this URL unfurling capability will be mostly guided by
issues created on clients. For the moment in status-mobile:

- https://github.com/status-im/status-mobile/issues/15906
- https://github.com/status-im/status-mobile/issues/15905

### Terminology

In the code, I've tried to stick to the word "unfurl URL" to really mean the
process of extracting metadata from a website, sort of lower level. I use "link
preview" to mean a higher level structure which is enriched by unfurled data.
"link preview" is also how designers refer to it.

### User flows

1. Carol needs to see link previews while typing in the chat input field. Notice
   from the diagram nothing is persisted and that status-go endpoints are
   essentially stateless.

2. Carol sends the text message with link previews in the RPC request
   wakuext_sendChatMessages. status-go assumes the link previews are good
   because it can't and shouldn't attempt to re-unfurl them.

```

3. The message was sent over waku and persisted locally in Carol's device. She
   should now see the link previews in the chat history. There can be many link
   previews shared by other chat members, therefore it is important to serve the
   assets via the media server to avoid overloading the ReactNative bridge with
   lots of big JSON payloads containing base64 encoded data URIs (maybe this
   concern is meaningless for desktop). When a client is rendering messages with
   link previews, they will have the field linkPreviews, and the thumbnail URL
   will point to the local media server.

```
 #+begin_src plantuml :results verbatim
   Client->>Server: GET /link-preview/thumbnail (media server)
   Server->>DB: Read from user_messages.unfurled_links
   Server->Server: Unmarshal JSON

 #+end_src
```

### Some limitations of the current implementation

The following points will become separate issues in status-go that I'll work on
over the next couple weeks. In no order of importance:

- Improve how multiple links are fetched; retries on failure and testing how
  unfurling behaves around the timeout limits (deterministically, not by making
  real HTTP calls as I did). https://github.com/status-im/status-go/issues/3498
- Unfurl favicons and store them in the protobuf too.
- For this PR, I added unfurling support only for websites with OpenGraph
  https://ogp.me/ meta tags. Other unfurlers will be implemented on demand. The
  next one will probably be for oEmbed https://oembed.com/, the protocol
  supported by YouTube, for example.
- Resize and/or compress thumbnails (and favicons). Often times, thumbnails are
  huge for the purposes of link previews. There is already support for
  compressing JPEGs in status-go, but I prefer to work with compression in a
  separate PR because I'd like to also solve the problem for PNGs (probably
  convert them to JPEGs, plus compress them). This would be a safe choice for
  thumbnails, favicons not so much because transparency is desirable.
- Editing messages is not yet supported.
- I haven't coded any artificial limit on the number of previews or on the size
  of the thumbnail payload. This will be done in a separate issue. I have heard
  the ideal solution may be to split messages into smaller chunks of ~125 KiB
  because of libp2p, but that might be too complicated at this stage of the
  product (?).
- Link preview deletion.
- For the moment, OpenGraph metadata is extracted by requesting data for the
  English language (and fallback to whatever is available). In the future, we'll
  want to unfurl by respecting the user's local device language. Some websites,
  like GoDaddy, are already localized based on the device's IP, but many aren't.
- The website's description text should be limited by a certain number of
  characters, especially because it's outside our control. Exactly how much has
  not been decided yet, so it'll be done separately.
- URL normalization can be tricky, so I implemented only the basics to help with
  caching. For example, the url https://status.im and HTTPS://status.im are
  considered identical. Also, a URL is considered valid for unfurling if its TLD
  exists according to publicsuffix.EffectiveTLDPlusOne. This was essential,
  otherwise the default Go url.Parse approach would consider many invalid URLs
  valid, and thus the server would waste resources trying to unfurl the
  unfurleable.

### Other requirements

- If the message is edited, the link previews should reflect the edited text,
  not the original one. This has been aligned with the design team as well.
- If the website's thumbnail or the favicon can't be fetched, just ignore them.
  The only mandatory piece of metadata is the website's title and URL.
- Link previews in clients should be generated in near real-time, that is, as
  the user types, previews are updated. In mobile this performs very well, and
  it's what other clients like WhatsApp, Telegram, and Facebook do.

### Decisions

- While the user typing in the input field, the client is constantly (debounced)
  asking status-go to parse the text and extract normalized URLs and then the
  client checks if they're already in its in-memory cache. If they are, no RPC
  call is made. I chose this approach to achieve the best possible performance
  in mobile and avoid the whole RPC overhead, since the chat experience is
  already not smooth enough. The mobile client uses URLs as cache keys in a
  hashmap, i.e. if the key is present, it means the preview is readily available
  (naive, but good enough for now). This decision also gave me more flexibility
  to find the best UX at this stage of the feature.
- Due to the requirement that users should be able to see independent loading
  indicators for each link preview, when status-go can't unfurl a URL, it
  doesn't return it in the response.
- As an initial implementation, I added the BLOB column unfurled_links to the
  user_messages table. The preview data is then serialized as JSON before being
  stored in this column. I felt that creating a separate table and the related
  code for this initial PR would be inconvenient. Is that reasonable to you?
  Once things stabilize I can create a proper table if we want to avoid this
  kind of solution with serialized columns.
