fix: update loop, ghost queue item, briefing card scroll trap

Browse Source 
- Update dialog no longer re-appears on every shell re-mount; check()
  is skipped if status is already available/upToDate/downloading
- Offline queue dequeue now happens before the mounted check, preventing
  ghost items when the widget disposes mid-drain
- Briefing digest card and messages now share a CustomScrollView so
  expanding the card doesn't trap the user without scroll access
