Created a generic PagedDatabaseObserver (common logic for conversation & gallery paged database queries and observation)
Updated the MediaGallery to use the PagedDatabaseObserver
Split the interaction and thread data queries for the conversationVC
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
Updated to the latest version of GRDB
Fixed an issue with db reentrant behaviour with the Attachment upload function
Finished up the updated 'sendNonDurability' functions
Fixed up quote attachment sending and retrieval
Validated attachment sending and retrieving is working correctly
Re-added the AttachmentUploadJob migration
Refactored the SignalApp class to Swift
Fixed a horizontal alignment issue in the ConversationTitleView
Fixed an issue where expiration timer update messages weren't migrated or rendering correctly
Fixed an issue where expiring messages weren't migrated correctly
Fixed an issue where closed groups which had been left were causing migration failures (due to data incorrectly being assumed to be required)
Shifted the Legacy Attachment types into the 'SMKLegacy' namespace
Moved all of the NSCoding logic for the TSMessage
Fixed a few job migration issues
Fixed an issue with the closed group key pair management (wasn't storing keys correctly)
Refactored the OWSSound (now Preferences.Sound)
Added the logic for the AttachmentDownloadJob and enabled jobs to be cascade deleted via interactions
Optimised the HomeViewModel database observation query (fetch specific columns so changes outside those don't trigger updates)
Updated to the latest GRDB (ran into a deadlock which should be fixed in a newer version)
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
