3 -
在AppSettings中添加VariableImportTemplate配置项，用于设置变量导入的默认参数（IsActive、PollingIn
terval、IsHistoryEnabled、HistoryDeadband）
4 - 修改AppSettings.Load()方法，优化配置加载逻辑
5 -
实现IVariableItemViewModelFactory和VariableItemViewModelFactory，使用工厂模式创建VariableItemVie
wModel实例
6 - 在ImportOpcUaDialogViewModel中使用工厂创建VariableItemViewModel实例，以应用默认配置
7 -
在SettingViewModel和SettingView中添加变量导入设置界面和相关属性（VariablePollingInterval、Variab
leIsActive、VariableIsHistoryEnabled、VariableHistoryDeadband）
8 - 移除VariableItemViewModel构造函数中的轮询间隔默认值设置，改由工厂模式设置
9 - 优化SplashViewModel中配置加载逻辑
10 - 移除MainView.xaml.cs中已注释的代码
11 - 调整VariableTableView.xaml的UI布局和菜单结构
12 - 注册IVariableItemViewModelFactory服务
这些修改主要实现了几个关键功能：
1. 引入了工厂模式来创建VariableItemViewModel实例，确保所有新创建的变量项都应用默认配置
2. 添加了变量导入模板设置，用户可以在设置界面自定义导入变量的默认属性
3. 对相关UI进行了调整和优化
