Subject: [PATCH] feat: auto-recreate user container on login if missing

Changes:
- If container exists but is not running: restart it
- If container_id exists but container was deleted: spawn new container
- If no container_id at all: spawn new container
- Adds detailed logging for container lifecycle

This ensures users always have a working container after login, even if the old one was deleted or didn't exist yet.
