3 1. 在MqttServer和MqttServerDto模型中添加IsConnect属性，用于跟踪连接状态
4 2. 重构MqttManagementService服务，使用事件驱动方式管理服务器状态变化
5 3. 实现MqttServerChangedEventArgs事件参数类，支持区分不同变更类型
6 4. 在IEventService中添加OnMqttServerChanged事件，实现事件通知机制
7 5. 优化数据存储结构，将MqttServers从ObservableCollection改为ObservableDictionary
8 6. 更新MqttServiceManager以正确处理连接状态和事件触发
9 7. 在WPF层更新UI以响应服务器状态变化
10 8. 删除不再需要的Helper类(DataServicesHelper, MessageHelper, SiemensHelper)
11 9. 在NLog配置中添加调试器输出目标以便调试
12 10. 完善VariableHistoryViewModel防止空引用异常
