Code Review

This pull request replaces dictionary .get() calls with getattr() when retrieving fields from response objects across deployments.py, files.py, and fine_tunes.py. The reviewer pointed out that if these response objects are standard Python dictionaries, getattr() will fail because dictionaries do not expose keys as attributes. The feedback recommends safely handling both dictionary and object types by checking if the response is an instance of dict before falling back to getattr().
