feat: 上一步/下一步支持woman步进撤销重做

- StepManager新增自由步进模式(无Config时):
  InitWomanSteps/RecordWomanStep/WomanStepPrevious/WomanStepNext
- PreviousStep/NextStep在_activeSteps为null时走woman步进
- TouchPositionHandler点击后通知StepManager.RecordWomanStep
- PageController在实验启动时调用InitWomanSteps初始化
- 上一步→woman回到上个位置+显示对应touchPoint
- 下一步→woman移到下个位置+显示对应touchPoint
