refactor(ops): 重构统计模块，支持日期参数化查询及代码质量优化

- 客流接口支持指定日期查询（getTrafficRealtime、getTrafficTrend、getAreaTrafficRealtime）
- 移除昨日对比趋势字段（yesterdayHourlyTrend），简化为单日期模式
- 漏斗图改为工单状态分布（FunnelItem→StatusDistributionItem），使用 SQL COUNT 替代内存分组
- 新增工牌队列统计（BadgeQueueStats），按 orderType 过滤避免跨类型数据混入
- 在线工牌计数仅统计 IDLE/BUSY 状态（排除 PAUSED/OFFLINE）
- 修复通配符导入和全限定类名引用，规范化 import 语句
