Add tooltip for expanded count

Enhance persistence for moderator preferences

- Add tooltip to moderation queue toggle showing number of items with detailed views expanded (based on global state, tooltip adapts to expanded/collapsed).
- Persist expanded/collapsed state per moderator in the database instead of localStorage, integrating with user preferences and Supabase backend.
