Refactor Dockerfiles and update paths

- Move database files to dedicated directory
- Separate ensemble startup script
- Pin Python version in ensemble Dockerfile
- Reorganize file copying steps
- Update working directory paths
- Clean up unused dependencies

This reorganization improves build consistency and separates concerns between database and ensemble deployments.
