Mahmoud-Emad 7001e8a2a6 refactor: externalize container and image base directories
- Add `base_dir` field to `ContainerFactory`
- Initialize `base_dir` from `CONTAINERS_DIR` env or user home
- Replace hardcoded `/containers` paths with `base_dir` variable
- Update image `created_at` retrieval to use `os.stat`
