2. List Mode Toggle: Verify that PreparationFormReorderableListDismissible renders when enableDismissible is true, and PreparationFormReorderableList renders when false.
3. Adding State: Verify that the input field (PreparationFormListField) appears only when preparationNameState.status is PreparationFormStatus.adding.
4. Interaction - Creation: Verify that onCreationRequested is called when the CreateIconButton is tapped.

Additional Context

• This widget depends on PreparationFormBloc and PreparationStepFormCubit.
• Tests will require wrapping the widget in a BlocProvider with mocked instances of these BLoCs to verify event dispatching.
