Merge remote-tracking branch 'origin/0.8.X' into 0.8.X

- 在 IWmsMaterialCoilService 中新增 getStatistics 方法用于汇总统计
- 在 WmsMaterialCoilController 中添加 /statisticsList 接口
- 在 WmsMaterialCoilMapper 中新增 selectStatistics 查询方法
- 在 WmsMaterialCoilMapper.xml 中实现统计 SQL 查询
- 在 WmsMaterialCoilServiceImpl 中实现统计业务逻辑
- 支持按筛选条件统计总毛重、总净重和总数
- 采用高性能查询方式只查询 sum/count 聚合数据
- 独立统计接口不影响原有分页查询功能
