The backend returns photo_path, photo_thumbnail_path, and photo_upload_date
from the AI auto-save feature, but the frontend Item interface was missing
these fields, causing images not to display in ItemDetailModal and InventoryTable.
Updated:
- frontend/lib/db.ts: Added missing photo fields to Item interface
- frontend/components/ItemDetailModal.tsx: Use photo_path first, fallback to image_url
- frontend/components/InventoryTable.tsx: Use photo_path first, fallback to image_url
This ensures the UI can now display photos saved by the auto-photo-save feature.
