本次提交对变量管理和数据处理进行了多项重构和优化：

Browse Source 
1.  重构变量管理服务:
      *   统一了单个和批量变量的更新逻辑，并引入 AutoMapper 进行对象映射，提高了代码的可维护性。
      *   增加了对 IsHistoryEnabled 属性变更的跟踪，允许系统对此类变更做出响应。

  2.  改进历史记录:
      *   HistoryProcessor 现在记录变量的 DisplayValue，使得历史数据与用户界面显示的值保持一致。

  3.  修正值转换逻辑:
      *   ValueConvertProcessor 在应用转换公式后，会同时更新变量的 NumericValue 和 DisplayValue，确保了数据在处理链中的一致性。
