refactor(content_management): update the BlocListener in create_source_page.dart. Instead of triggering a full data reload, it will now dispatch the new SourceAdded event. This event passes the newly created source object directly to the ContentManagementBloc, which will add it to the list locally for an immediate and efficient UI update.
