Updated to the latest version of GRDB
Renamed some variables for clarity
Updated the "seed viewed" banner on the HomeVC to be driven by a database setting to be consistent with other UI changes
Updated the migrations to indicate progress (Potential to base progress for the "processing" sections on the file size of the legacy database)
Updated the JobRunner to properly support concurrent queues for sending/receiving (other queues are still serial)
Added the typing indicator logic into the ConversationVC
Put code into SUKLegacy for connecting to the YDB database
Fixed a couple of minor UI bugs with the GalleryRailView
Updated the media gallery selection screen to use the appropriate system theme colouring (was painful to randomly swap from dark mode to like for one screen...)
Added an alert for when the database migration fails
Deleted the legacy migrations (manually applying any unapplied changes as part of the YDB to GRDB migration process)
Fixed a number of scrolling behaviours in the ConversationVC
Fixed a bug with the PagedDataObserver when observing associated data (multiple associations with a single paged result were broken)
Fixed a bug with the PagedDataObserver where it would trigger updates for new entries even if the user is offset from the latest data
Fixed a bug where marking as read wasn't working properly
Fixed a bug where outgoing messages were being considered unread
Added an error state for a failed attachment send
Renamed a few types for clarity
Resolved a bunch of TODOs
Removed the logic for 'oversizedText' (not sent by either iOS or Android and not handled at all by desktop)
Updated the HomeViewModel (and ConversationCell) to use the same query model as Global Search
Added an 'albumIndex' property to the InteractionAttachment so we can enforce a correct order (apparently SQLite doesn't do this by default)
Updated the YDB to GRDB migration to avoid creating GroupMembers if the current user isn't a member of a ClosedGroup (be consistent with the running logic)
Updated the attachment description logic to be consistent throughout
Cleaned up the Interaction preview generation logic
Got mentions working again
Got typing indicators working again
Got the notification sound and preview preferences working
Fixed a few issues with attachment image loading
Fixed an issue where enum settings weren't getting stored correctly
Fixed a couple of issues around the duplicate messages handling
Fixed a few issues with ClosedGroup polling and ClosedGroup control message handling
Started working through updating the MediaGallery
Refactored the AppDelegate from Objective C to Swift
Updated the HomeVC to use GRDB
Refactored a number of the Job types to be driven via GRDB and the new JobRunner
Fixed a bug where the LinkPreviewView wouldn't render correctly in dark mode
