refactor(content_management): update the BlocListener in create_category_page.dart. Instead of dispatching the old LoadCategoriesRequested event (which caused a full reload), it will now dispatch the new CategoryAdded event. This event carries the newly created category object directly to the ContentManagementBloc, which will add it to the list locally for an instant UI update.
