fix(aiot): 修复告警汇总应用名更新不同步问题

问题：应用名修改后，告警列表显示正确，但告警汇总仍显示旧名称
原因：device_id字段混用app/stream和camera_code格式，汇总直接显示device_id
影响：用户无法看到摄像头当前的实际应用名

修复内容：
- 告警汇总API实时查询WVP获取当前摄像头信息
- 支持camera_code格式查询（通过cameraCode参数）
- 支持app/stream格式查询（通过列表筛选）
- 查询失败时回退显示device_id

修复效果：
✅ 应用名修改后告警汇总立即同步
✅ 兼容两种device_id格式
✅ 降级策略保证稳定性
