feat(ui): 更新UiRouterBase以支持基于键值的页面导航

- 添加PeekKey方法获取页面栈顶元素的键值
- 修改Peek方法返回IUiPageBehavior对象而不是类型名称
- 更新IsTop和Contains方法使用键值比较替代类型名比较
- 在UiTransitionEvent中使用PeekKey获取来源UI键值
- 为CanvasItemUiPageBehavior添加key参数和Key属性实现
- 在IUiPageBehavior接口中定义Key属性
- 更新IUiRouter接口定义新的PeekKey和Peek方法
- 添加必要的using引用和异步任务配置
