refactor(content_management): update the _onSubmitted method in edit_source_bloc.dart. When a source is successfully updated, I'll set the updatedAt timestamp and then emit the complete updatedSource object along with the success status. This makes the updated item available in the BLoC's state, which is the final piece required before we can move on to updating the main ContentManagementBloc.
