Subject: [PATCH] Improve Docker build caching for staging workflow

- Add registry cache persistence to fallback when GHA cache expires
- Optimize static-assets stage with selective COPY for frontend files
- Reduces context from 44MB to 3.2MB, preventing cache invalidation on backend changes
- Backend-only changes no longer trigger unnecessary frontend rebuilds
