功能增强：添加 InputDialog 并改进变量管理功能

- 新增 InputDialog 组件：
     - 添加了 InputDialog.xaml 和 InputDialog.xaml.cs 文件
     - 创建了 InputDialogViewModel.cs，继承自 DialogViewModelBase<string?>
     - 实现了可重用的输入对话框，支持自定义标题、消息、标签和占位符

   - 完善变量管理服务：
     - 在 MappingProfile.cs 中添加了 VariableDto 到 VariableDto 的映射配置
     - 在 VariableManagementService.cs 中注入 IMapper 依赖项
     - 修改了 UpdateVariablesAsync 方法，使用 AutoMapper 进行更安全的更新操作

   - 扩展变量表功能：
     - 在 VariableTableViewModel.cs 中添加了 ModifyConversionFormula 命令
     - 实现了批量修改变量转换公式功能，支持用户通过对话框输入新公式
     - 添加了相应的 UI 通知和错误处理
     - 在 VariableTableView.xaml 中添加了"修改数值转换公式"菜单项

   - 集成 InputDialog 到对话框服务：
     - 在 DialogService.cs 中注册了 InputDialogViewModel 和 InputDialog 的映射关系
