Pascal Precht d0e0deac95 feat: introduce `discord_message_authors` persistence APIs 
This introduces a new table to store discord message authors.
The main reason this table is being introduce is so that we don't have
to duplicate discord message author information in the `user_messages`
table when importing discord communities (ongoing work).

In addition to the table there are also two new APIs on the messenger
persistence layer (which are later used in the import logic):

- `HasDiscordMessageAuthor`
- `SaveDiscordMessageAuthor`

Closes #2759

Hash ratchet encryption

encryptor.GenerateHashRatchetKey() generates a hash ratchet key and stores it in in the DB. There, 2 new tables are created: hash_ratchet_encryption and hash_ratchet_encryption_cache. Each hash ratchet key is uniquely identified by the (groupId, keyId) pair, where keyId is derived from a clock value.

protocol.BuildHashRatchetKeyExchangeMessage builds an 1-on-1 message containing the hash ratchet key, given it's ID.

protocol.BuildHashRatchetMessage builds a hash ratchet message with arbitrary payload, given groupId. It will use the latest hash ratchet key available. encryptor.encryptWithHR encrypts the payload using Hash Ratchet algorithms. Intermediate hashes are stored in hash_ratchet_encryption_cache table.

protocol.HandleMessage uses encryptor.decryptWithHR fn for decryption.
