- DB migration 0012: add photo_key and photo_uploaded_at columns to pets table
- S3 client utility (apps/api/src/lib/s3.ts): presigned PUT/GET, delete via Rook-Ceph RGW
- API photo routes on petsRouter:
- POST /:petId/photo/upload-url — returns presigned PUT URL + object key
- POST /:petId/photo/confirm — records key in DB after successful upload
- DELETE /:petId/photo — deletes from storage and clears DB
- GET /:petId/photo — returns presigned GET URL
- RBAC: all staff roles (manager, receptionist, groomer) may upload/delete photos;
restructured index.ts guards so groomer-accessible photo paths don't overlap
with the manager/receptionist-only general pets write guard
- Frontend PetPhotoDisplay: responsive image with shimmer skeleton and paw placeholder
- Frontend PetPhotoUpload: client-side resize to max 1200px, XHR with progress,
presigned PUT flow — binary data never passes through the API server
- Wired both components into Clients.tsx staff portal pet cards
- Unit tests: 14 test cases covering all four routes (happy path + error cases)
