feat: 实现 IoT 卡轮询系统(支持千万级卡规模)
All checks were successful
构建并部署到测试环境(无 SSH) / build-and-deploy (push) Successful in 6m35s

实现功能:
- 实名状态检查轮询(可配置间隔)
- 卡流量检查轮询(支持跨月流量追踪)
- 套餐检查与超额自动停机
- 分布式并发控制(Redis 信号量)
- 手动触发轮询(单卡/批量/条件筛选)
- 数据清理配置与执行
- 告警规则与历史记录
- 实时监控统计(队列/性能/并发)

性能优化:
- Redis 缓存卡信息,减少 DB 查询
- Pipeline 批量写入 Redis
- 异步流量记录写入
- 渐进式初始化(10万卡/批)

压测工具(scripts/benchmark/):
- Mock Gateway 模拟上游服务
- 测试卡生成器
- 配置初始化脚本
- 实时监控脚本
