feat(wms): 新增第三个报表统计——冷硬卷统计

- 在IWmsMaterialCoilService中添加getCoilTrimStatistics方法
- 在WmsMaterialCoilController中新增trimStatistics接口
- 在WmsMaterialCoilMapper中添加selectCoilTrimStatistics查询方法
- 在WmsMaterialCoilMapper.xml中实现切边统计数据SQL查询
- 在WmsMaterialCoilServiceImpl中实现切边统计业务逻辑
- 新增CoilTrimRawVo、CoilTrimStatisticsVo和TrimWidthStatisticsVo数据传输对象
- 按厚度、宽度、切边要求（净边/毛边）统计钢卷数量和重量
- 实现数据分组和排序功能，支持前端展示需求
