feat: Add Ombi request filtering and search

- Add request filters UI (type, status, sort, search)
- Implement dual-layer filtering (server + client)
- Add ombiFilters utility for consistent filtering logic
- Persist filter preferences in localStorage
- Add SSE support for real-time Ombi request updates
- Add webhook endpoints for Ombi integration
- Update OpenAPI spec for new endpoints
- Add unit tests for filter logic and UI
- Add integration tests for Ombi routes
