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