feat: ranking in-progress indicator persists across all admin users

- Create snapshot with status RUNNING before AI call starts
- Update to COMPLETED/FAILED when done
- Dashboard derives rankingInProgress from server snapshot status
- All admins see the spinner, not just the one who triggered it
- Poll snapshots every 3s so progress updates appear quickly
