Subject: [PATCH] fix: add backwards compatibility properties for
 container_id/container_port

User model now provides container_id and container_port as properties that
work with the new UserContainer relationship. This allows legacy code in
api.py to continue working without modifications. The properties automatically:
- Read from the primary (first) container
- Create a primary container on first write
- Maintain backwards compatibility with single-container API
