fix: Refactor devcontainer to use base Ubuntu with Docker-in-Docker

- Switch from docker-compose service to base Ubuntu container
- Add Docker-in-Docker to run docker-compose inside Codespace
- This provides git access and full dev environment
- Superset services run via docker-compose from within the container
