feat(revenue): 远传集抄模块 - 批量抄表+大表监控DN80+任务管理+数据质量分析

- DDL: mr_task, mr_meter_reading, mr_large_meter_monitor, mr_data_quality
- Entity: MeterReading, LargeMeterMonitor, MeterReadingTask, MeterDataQuality
- Mapper: 4个Mapper + 自定义SQL(异常分布/日摘要/活跃报警/质量趋势)
- Service: 批量抄表(异常检测)+大表监控(流量报警)+任务管理+质量评分
- Controller: 22个API端点(抄表/大表/质量/任务)
- Test: 16个单元测试(异常检测/评分计算/报警阈值/实体逻辑)

Closes #58
