- 在IWmsLeaveRequestService接口中新增按请假类型、部门、月份统计的方法
- 在IWmsMealReportService接口中新增按餐别、部门、日期统计的方法
- 在WmsLeaveRequestController中添加请假统计报表相关API端点
- 在WmsMealReportController中添加报餐统计报表相关API端点
- 在WmsLeaveRequestServiceImpl中实现请假统计报表的数据查询逻辑
- 在WmsMealReportServiceImpl中实现报餐统计报表的数据查询逻辑
- 使用QueryWrapper构建统计查询条件，支持多维度筛选和分组统计
- 统一返回Map格式的统计数据，便于前端展示报表图表
