feat(box): 重构装箱清单功能并增强序列号生成服务

- 重命名 BoxController 为 BoxListController
- 扩展 BasdeSerialNumberControllerService 中的 generateSerialNumber 方法，支持自定义中间字符串和长度参数
- 在 BoxListController 中新增 getItems 和 getForwards 接口用于获取明细和代发物料列表
- 实现装箱清单 Excel 导出功能，包含基础信息和物料清单数据
- 新增 MaterialCodeForwardImportDTO 数据传输对象用于代发物料导入导出
- 实现代发物料的 Excel 导入导出功能，支持批量处理
- 在 PackagingCodeController 中使用序列号服务生成包装码编号
- 扩展 ShipmentMaterialCodeItemVO 和 ShipmentMaterialCodeQRVO 对象，增加状态和序号字段
- 新增数据库查询方法 getByPackagingCodeId 和 getItemsVOById
- 更新 MyBatis 映射文件，优化查询逻辑并添加排序功能
