Refactor:

- 重构了 VariableTableDataService 中的 AddVariableTable 方法，使其返回值从 bool 变为新表的 ID
  (int)。这使得服务层更加健壮，并能向调用方提供新创建实体的确切ID。

  Fix:
  - 修复了 DeviceDetailViewModel 在创建变量表后UI不自动更新的Bug。现在视图模型会正确地将新表添加到UI集合中，确保了界面的即时刷新。

  Feat:
  - 为 DeviceDetailViewModel 添加了 IsBusy
  状态。现在“添加”、“编辑”和“删除”等异步操作会更新此状态，防止了用户重复点击，并允许UI在处理期间显示加载指示，提升了用户体验。
