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)
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
