refactor(iot): 重构客流计数器为增量累加模式，支持 people_out

- 删除旧 TrafficCounterBaseRedisDAO（基准值模式），新增 TrafficCounterRedisDAO
  支持阈值计数器（达标后重置）和当日累积统计（用于报表）
- TrafficThresholdRuleProcessor 改为增量原子累加，消除基准值校准逻辑
- CleanRuleProcessorManager 路由增加 people_out 支持
- TrafficCounterBaseResetJob 改为每日清除阈值计数器，持久化职责移交 Ops 模块
- 使用 SCAN 替代 KEYS 避免阻塞 Redis
