WinUI3/WASDK问题：无法在CarouselPage中添加Input.Toggle控件

你遇到的错误是因为Windows 11小部件的Carousel组件（微软对Adaptive Cards的私有扩展）不允许在CarouselPage的items中直接放置Input类控件。Input.Toggle这类表单控件仅支持在支持表单交互的顶层容器中使用，CarouselPage仅兼容静态展示类控件（如TextBlock、Image、Container等）。

下面是可行的替代方案——用视觉元素模拟复选框，并通过交互动作实现状态切换：

方案说明 #

1. 视觉模拟：用两张图标（勾选/未勾选）模拟复选框状态，通过isVisible属性控制显示/隐藏
2. 交互逻辑：点击容器时，通过Action.ToggleVisibility切换图标展示状态，同时用Action.Execute将状态变更同步到你的业务逻辑（如本地存储或后端接口）
3. 兼容性：该方案完全符合CarouselPage的控件支持规则，不会触发解析错误
