Note

Prep schedule updates and edit flow

• Switch updatePreparationByScheduleId API call from POST to PUT.
• Introduce PreparationEditDraftCubit to hold draft state across /preparationEdit navigation; editor saves to draft and caller reads/clears after return.
• Update PreparationEditForm to read/set draft, and router /preparationEdit to no longer require extra param.
• Replace Dismissible list with SwipeActionCell swipe-to-delete in PreparationFormReorderableList; remove enableDismissible flag and delete preparation_form_reorderable_list_dissmissible.dart.
• Update schedule form to open editor using draft, apply changes on return, and clear stale drafts.
