- Add djangorestframework-simplejwt==5.3.1 to requirements-docker.txt
- Configure REST_FRAMEWORK with JWTAuthentication and SIMPLE_JWT settings
- Create admin_api Django app with AdminLoginView, MeView, HealthView
- Wire /api/v1/ routes without touching existing /api/ mobile endpoints
- Resolve pre-existing events migration conflict (0010_merge)
- Superuser admin created for initial authentication
