Implement recent checks API endpoint for dashboard

- Replace placeholder implementation with real database query
- Add cross-project checks retrieval for authenticated users
- Include detailed check information with hops, timing, and metadata
- Add proper database joins across checks → projects → organizations → memberships
- Format response to match frontend expectations
- Rebuild API with updated implementation

Fixes dashboard checks history display - now shows real tracking data instead of empty placeholder
