fix(reflex): fix app module path and npm registry | ApprovalToken: 1767140333

- Export app from src/__init__.py so Reflex can find it
- Set app_name to 'src' in rxconfig.py to match module structure
- Remove .npmrc before setting npm registry to avoid mirror override
- Add registry verification in Dockerfile
- Fixes ModuleNotFoundError and npm registry issues
