frontend: route all photo queries through sidecar timeline proxy

- listPhotos → /api/sidecar/timeline (was /photos)
- countPhotos → /api/sidecar/timeline (was /photos)
- hasPhotosMatching → /api/sidecar/timeline (was /photos)
- Sidecar handler forwards X-Count header for countPhotos()
- Sidecar adjusts X-Count to reflect post-filtered count
