Microsoft Lists时间线格式问题：富文本列显示HTML代码

问题原因 #

将「Description」列转为「Enhanced rich text」后，该字段存储的是包含HTML标签的富文本内容，原JSON中使用的txtContent属性会把所有内容当作纯文本输出，导致HTML代码直接显示。

解决方案 #

把对应字段的txtContent替换为innerHTML，让浏览器解析HTML标签并渲染格式化文本。

修改点说明 #

仅修改了「Description」字段对应的渲染部分：将"txtContent": "[$Description]"替换为"innerHTML": "[$Description]"。
