feat(navigation): 重构导航系统引入导航参数和类型

- 新增NavigationType枚举定义导航类型
 - 新增NavigationParameter类用于传递导航参数
 - 重构INavigationService和INavigatable接口
 - 更新NavigationService实现以支持新的导航方式
 - 更新DeviceDetailViewModel, DevicesViewModel, VariableHistoryViewModel, VariableTableViewModel, MqttsViewModel等
 - 使ViewModelBase实现INavigatable接口
 - 更新MainView中的菜单选择导航逻辑
 - 优化VariableHistoryView界面布局，添加返回变量表按钮
