feat: extend boxing module to support accessory items

- Add PendingAccessory schema and pending_accessories to BoxInfoResponse
- Add item_type field to BoxItemDetail, CurrentZongpaiBox, BoxSaveRequest, BoxSaveResponse
- Query pending (unboxed) accessories in get_box_info
- Branch save_box_record to skip ERP validation for accessory items
