refactor: 流量系统重构 — 增量累加算法 + 日粒度缓冲 + 旧详单清理
All checks were successful
构建并部署到测试环境(无 SSH) / build-and-deploy (push) Successful in 7m16s

核心改造:
- 增量算法:流量计算从覆盖式改为增量累加(gateway - lastReading),支持上游运营商重置检测
- 日流量缓冲:insertDataUsageRecord 改为 Redis INCRBYFLOAT,每日凌晨落盘到 tb_card_daily_usage
- 运营商:新增 data_reset_day 字段(联通=27,其余=1)
- IoT卡:新增 last_gateway_reading_mb 字段存储上次网关读数
- 查询层:新建 TrafficQueryService 合并 Redis(今日)+ DB(历史)数据源
- 清理:删除 DataUsageRecord model/store,移除 polling_handler 旧引用

迁移:000094-000097(carrier字段、iot_card字段、数据初始化、日流量表)
