refactor(content_management): update the BlocListener in edit_source_page.dart. When an edit is successful, it will dispatch the SourceUpdated event, passing the updated source object directly to the ContentManagementBloc. This completes our UI refactoring, ensuring all create and edit operations result in an efficient local list update rather than a full reload.
