1. 创建了 BatchImportVariablesEventArgs 事件参数类

2. 在 IEventService 接口中添加了 OnBatchImportVariables 事件和 RaiseBatchImportVariables 方法
   3. 在 EventService 实现中添加了对新事件的支持
   4. 在 IVariableManagementService 接口中添加了 BatchImportVariablesAsync 方法
   5. 在 VariableManagementService 中实现了该方法，并在批量导入后触发事件
   6. 更新了 VariableTableViewModel 以使用 IVariableManagementService 而不是 IVariableAppService
