Got the updated file upload working
Removed the legacy 'room' header
Consolidated a number of types between SOGS, FileServer and general requests
Updated the OnionRequestAPI to deal with a Data payload (rather than encoding it to a string and then back to data)
Updated the join open group method to retrieve the capabilities as part of the initial request
Updated the OpenGroupManager to require a transaction to be passed to the various 'handler' methods (allowing for everything to be processed within a single transaction)
Fixed a few issues where we weren't storing the timestamp for open group messages and DMs which could result in duplicate messages
Fixed an issue where we were setting the timestamp value for messages sent to an open group without converting it to be milliseconds to be consistent with other messages
Fixed an issue where the BatchRequestInfo could incorrectly flag it's response as failing to parse even though the type was optional
Fixed a bug where the open group would re-fetch all messages every other time
Fixed a bug where the long press context menu wouldn't appear after failing to delete a message
Fixed a bug where joining an open group would trigger the join behaviour and APIs twice
Moved the BlindedIdMapping retrieval logic to ContactUtilities so it's reusable
Added the 'outbox' endpoints (need testing as they aren't deployed to test yet)
Fixed a couple of build issues where I missed a couple of calls to removed functions
Fixed a EXC_BAD_ACCESS issue where the 'poll' function could be called from multiple threads (which accesses and mutates variables)
Cleaned up the MessageRequestResponse handling a little
Renamed the setter for the SOGS 'Server' object for consistency
Updated the Curve25519Kit repo to use an Oxen fork
Updated the MockDataGenerator to accomodate the latest changes
Updated the ConversationVC to better support getting replaced when the conversion from blinded to unblinded happens while on that screen
Added a cache for the mapping between blinded ids and standard ids (gets cached whenever a valid match is found)
Added a migration to remove the old 'authToken, 'lastMessageServerId' and 'lastDeletionServerId' collections (redundant in SOGS V4)
Pointing Curve25519 to use a fork that exposes an XEd25519 conversion method
Fixed an issue where I had broken all message sending due to the SnodeAPI casting Onion responses to `Any`
Added a few types to make the code more readable
Added the inbox request to the polling
Added a couple of properties to the TSContactThread to indicate the originating open group to support SOGS DMs
Added code to store the latest message id for an open group inbox
Added a bunch of documentation from the API docs into the OpenGroupAPI (and associated models)
Updated the OpenGroupAPI to match the latest docs
Fixed the incorrect structure of the SendDirectMessageRequest
Fixed an incorrect inbox endpoint path
Tweaked the batch response handling so it wouldn't fail to parse all responses if a single one failed
Renamed IdPrefix to SessionId.Prefix and cleaned up the type to be more readable & self-documenting
Updated the OpenGroup polling to run on a non-main thread
Updated the TSGroupModel to store moderatorIds as well as the adminIds (new endpoint is only going to give diffs)
Updated the BatchRequest to support json, base64 encoded strings and raw bytes for it's body
Replaced the 'lastMessageServerID' methods with 'OpenGroupSequenceNumber' methods (since we have swapped the property over)
Added an alert when banning fails (previously it would fail silently)
Fixed a bug where sent blinded messages were appearing as incoming messages
Fixed a bug where the OpenGroup infoUpdates wasn't getting decoded correctly
Fixed an issue where the ConversationVC wouldn't become the first responder again after the ban alerts disappeared
Fixed an issue where I'd incorrectly used the message 'seqNo' in place of the message server id
Fixed an issue where open group messages were setting their `sentTimestamp` to seconds instead of milliseconds for incoming messages
Got the updated blinding logic working (at least when authenticating a request - still need to deal with message signing and verification)
Storing the server capabilities in the database now so we can correctly blind requests based on them
Renamed the remaining 'v2' functions and classes to just be 'OpenGroup' since there isn't a 'V2' anymore
Cleaned up a few TODOs and functions
Added some new properties to the OpenGroupV2
Moved a number of methods and variables from OpenGroupAPI to OpenGroupManager (anything doing actual logic)
Moved the message signing into the OpenGroupAPI (since that's the only place it happens)
Renamed remaining old model classes to start with 'Legacy' to make clean up easier
Updated the OpenGroupAPI poll method to use the same logic as it previously did to determine if it should retrieve recent messages or messages since the last one
