- Ensure async track_janitor_event across all call sites
- Improve error handling in monitor request tracking (already in place)
Important Fixes:
- Replace fire-and-forget Redis with background persistence worker
- Add time-based expiry for completed requests/errors (5min cleanup)

Frontend Enhancements:
WebSocket Real-time Updates:
- Add WebSocket endpoint at /monitor/ws for live monitoring
- Implement auto-reconnect with exponential backoff (max 5 attempts)
- Add graceful fallback to HTTP polling on WebSocket failure
- Send comprehensive updates every 2 seconds (health, requests, browsers, timeline, events)
UI/UX Improvements:

- Add flex layout to browser section header
Testing:
- Add test-websocket.py for WebSocket validation
- All 7 integration tests passing successfully
Summary: 563 additions across 6 files
- Introduced a demo script (`demo_monitor_dashboard.py`) to showcase various monitoring features through simulated activity.
- Implemented a test script (`test_monitor_demo.py`) to generate dashboard activity and verify monitor health and endpoint statistics.
- Added a logo image to the static assets for branding purposes.
- Add tables field to CrawlResult model while maintaining backward compatibility
- Update async_webcrawler.py to extract tables from media and pass to tables field
