feat(apple): storage screen, About content, and fixes

- Settings: add Storage screen (size breakdown + delete-all-transfers) and
  expand About (what it is/isn't, privacy & security, license/source)
- Move Report a bug to a toolbar sheet (cancel-only unless empty)
- Send progress: derive the list-row bar from receiver delivery status so it
  clears once every receiver completes
- Fixes: iPad orientations, onChange(of:) iOS 17 API, weak-self captures,
  invalid SF Symbol, macOS bug-report form labels; bump core build target to
  match the app (18.2/15.0)
