完整Playwright E2E测试：5套件21个测试全部通过（2.8分钟）

套件1: 管理API控制测试（7个）- 认证/启停/刷新/路由
套件2: 采集数据全链路验证（6个）- 原始JSON/结构化记录/机床状态/地址状态/字段映射/计数递增
套件3: 产量分段跟踪验证（3个）- 段自动创建/零件数更新/停止时结账
套件4: 异常处理与恢复验证（3个）- 不可达容错/恢复采集/失败日志
套件5: 心跳上报验证（2个）- running心跳/stopped心跳

关键技术决策：
- 使用mysql2直连数据库验证数据落库（log_collect_raw/cnc_collect_record等7张表）
- 轮询等待重试完成（3次重试×30秒=90秒）避免固定等待
- stop→改URL→start 强制重建worker（refresh不更新已存在worker的URL）
- 模拟器网关API动态启动模拟端口，DB URL动态更新
