test(aiot): 添加离岗告警完整流程集成测试

测试完整业务流程:
1. 人员上岗确认
2. 人员离开ROI
3. 离岗确认 → OFF_DUTY_COUNTDOWN
4. 倒计时结束 → ALARMED (验证告警无 duration_minutes，有 first_frame_time)
5. 创建告警记录 (验证 duration_ms=None)
6. 人员返回 → CONFIRMING_ON_DUTY
7. 回岗确认 → ON_DUTY (验证发送 resolve 事件)
8. 更新告警记录 (验证 duration_ms 已填充)

测试验证点:
- 告警触发时不包含 duration_minutes
- 告警创建时 duration_ms=NULL, last_frame_time=NULL
- resolve 事件包含正确的 duration_ms 和 last_frame_time
- 告警状态正确变更为 CLOSED/DONE
