- 修改 CreateDeviceWithDetailsAsync 方法，在数据库创建成功后自动添加到内存
- 修改 UpdateDeviceAsync 方法，在数据库更新成功后自动更新内存
- 修改 DeleteDeviceByIdAsync 方法，在数据库删除成功后自动从内存移除
- 修改 ToggleDeviceActiveStateAsync 方法，在数据库切换激活状态后更新内存
2. 更新 DeviceDataService 类：
- 移除了在 AddDevice 方法中的独立 AddDeviceToMemory 调用
- 移除了在 DeleteDevice 方法中的独立 RemoveDeviceFromMemory 调用
- 为 UpdateDevice 方法添加了注释，说明内存自动更新
3. 更新 DeviceMonitoringService 类：
- 在 OnDeviceActiveChanged 方法中使用 Task 运行异步的 UpdateDeviceAsync 调用
4. 更新接口文档：
- 在 IDeviceManagementService 接口中更新了内存操作方法的注释，说明通常由其他操作自动调用
