Implement reactive sorting for IDAA Archives

- Forced priority archives to the top of the list.
- Implemented descending (DESC) sort by the 'sort' field within groups.
- Added a sort selector to the archive list component.
- Centralized sorting logic in-memory within LiveQuery for immediate reactivity.
