refactor(content_management): update the BlocListener in edit_headline_page.dart. When an edit is successful, it will now dispatch the new HeadlineUpdated event, passing the updated headline object directly to the ContentManagementBloc. This allows the main list to update the specific item locally, which is much more efficient than reloading the entire list.
