feat: add registry config, image upload/download, and OCI format support

Backend:
- Add registry_address configuration API (GET/POST)
- Add tar image upload with OCI and Docker format support
- Add image download with streaming optimization
- Fix blob download using c.Send (Fiber v3 SendStream bug)
- Add registry_address prefix stripping for all OCI v2 endpoints
- Add AGENTS.md for project documentation

Frontend:
- Add settings store with Snackbar notifications
- Add image upload dialog with progress bar
- Add download state tracking with multi-stage feedback
- Replace alert() with MUI Snackbar messages
- Display image names without registry_address prefix
