1. 向 VariableTableManagementService 添加了 IEventService 依赖
2. 将内存操作和事件触发逻辑合并到数据库操作方法中：
- CreateVariableTableAsync 现在会在数据库创建后自动添加到内存并触发事件
- UpdateVariableTableAsync 现在会在数据库更新后自动更新内存并触发事件
- DeleteVariableTableAsync 现在会在数据库删除后自动从内存移除并触发事件
3. 从类中删除了独立的内存操作方法
4. 从接口中移除了内存操作方法
5. 更新了所有调用这些服务的代码，使它们不再调用已删除的内存方法
6. 扩展了 IEventService 以支持 VariableTableChanged 事件
