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
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
Added migrations for contacts and started working through thread migration (have contact and closed group threads migrating)
Deprecated usage of ECKeyPair in the migrations (want to be able to remove Curve25519Kit in the future)
