fix(tests): fix TestGetFullConfigException using PropertyMock on module-level settings

The test was using patch.object(type(settings), "onedrive_client_id", property(...))
to make settings.onedrive_client_id raise. Pydantic v2 Settings fields are not plain
Python descriptors so this approach raises AttributeError.

Fix: patch app.api.onedrive.settings with a MagicMock whose onedrive_client_id
is a PropertyMock(side_effect=Exception), which correctly triggers the except
branch in get_onedrive_full_config and returns {"status": "error"}.
