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)
