- Add type-only filter to notification repo/service (previously only
worked with type+read=false together)
- Dashboard widget now fetches all recent notifications (mentions +
replies, both read and unread) instead of unread mentions only
- Update component heading and show type label per row
Root cause: Berit's mentions were read=true, so the unread-only filter
returned 0 results. The recent docs widget had no REVIEWED documents
because 'marking ready' sets metadata_complete, not status=REVIEWED.
Recent docs now shows all uploads without a status filter.
