Fix 5 TestFlight crash types from builds 250-254

- Fix BGTaskScheduler assertion crash on Mac Catalyst by guarding all
  iOS background task APIs with isMacCatalystApp check
- Fix iPad popover crash in UIPopoverPresentationController by adding
  .presentationCompactAdaptation(.sheet) to all 27 confirmationDialogs
- Fix SwiftData assertion crash when accessing deleted Bookmark model
  properties during SwiftUI hit testing in BookmarkRowView
- Fix UICollectionView invalid item count crash on queue swipe-to-delete
  by using ID-based removal with withAnimation instead of stale index
- Fix Range crash in storyboard download when storyboardCount is zero
