Implement background generation for monthly SN/PN ZIP archives and expose completion through in-app notifications.

- add GeneratedFleetArchive persistence model with expiry metadata
- add archive request/download endpoints and Celery background tasks
- emit notification stages for requested/completed/failed archive jobs
- update calendar bulk download actions to trigger async requests
- add notification modal actions to download generated ZIP files
- extend backend tests for async archive request and download flows
