  iOS background task APIs with isMacCatalystApp check

  .presentationCompactAdaptation(.sheet) to all 27 confirmationDialogs
- Fix SwiftData assertion crash when accessing deleted Bookmark model
  properties during SwiftUI hit testing in BookmarkRowView

  by using ID-based removal with withAnimation instead of stale index
