1. 创建了 DeviceStateType 枚举来区分状态类型（激活/连接） 2. 创建了 DeviceStateChangedEventArgs 统一事件类 3. 更新了 IEventService 接口，将两个事件合并为一个 4. 更新了 EventService 实现以支持新事件 5. 更新了所有相关服务（DeviceMonitoringService, OpcUaServiceManager, S7ServiceManager, DeviceDataService, DeviceItemViewModel） 关键优点： - 减少了事件类型的数量，简化了事件系统 - 为设备状态变化提供了一致的处理方式 - 保持了向后兼容性，将旧类标记为 [Obsolete]
