fix: add GET /archive/:tab endpoint, fix archive loading spinner

- Added GET /polymarket/:agentId/archive/:tab endpoint (trades, exits, alerts, events)
- Returns archived rows from *_archive tables with count
- Gracefully returns empty result if archive table doesn't exist yet
- Dashboard archive toggle now handles errors instead of spinning forever
- Fixed archive API call using selectedAgent instead of agentId variable
