Fix history pagination and status panel issues

- Fix history pagination: use retriever's built-in maxPages parameter instead of broken date-based cursor
- Fix status panel: correct API endpoint from /api/dashboard/status to /api/status
- Background fetch now properly fetches up to 1000 records (10 pages * 100 records)
- Status panel will now display details instead of 'Loading Status...'
