feat(delivery): 新增钢卷绑定信息查询功能并优化发货单明细校验

- 在 WmsDeliveryWaybillDetailMapper 中新增按钢卷ID批量查询和单个查询绑定来源信息的方法
- 在 Mapper XML 文件中新增 WmsCoilBindInfoResult 结果映射和两个查询SQL
- 在 WmsDeliveryWaybillDetailServiceImpl 的数据校验方法中实现钢卷重复绑定检查
- 新增 WmsCoilBindInfoVo 类用于封装钢卷绑定信息
- 在 WmsMaterialCoilBo 中新增 excludeBound 和 includeBindInfo 参数控制绑定逻辑
- 在 WmsMaterialCoilServiceImpl 中实现钢卷列表的绑定信息查询和排除逻辑
- 在 WmsMaterialCoilVo 中新增绑定相关字段用于前端显示
- 优化发货单明细保存前的数据校验，防止钢卷重复绑定并提供详细的绑定来源提示
