feat(delivery): 添加按负责人查询已绑定钢卷功能

- 在 IWmsDeliveryWaybillDetailService 中新增 getBoundCoilIdsByPrincipal 方法
- 在 WmsDeliveryWaybillDetailController 中添加 coilListByPrincipal 接口
- 实现 WmsDeliveryWaybillDetailServiceImpl 中的 getBoundCoilIdsByPrincipal 逻辑
- 使用 LambdaQueryWrapper 查询指定负责人的运单及关联钢卷信息
- 添加参数校验和空值处理机制
