【问题】页面设计器本地启动时添加静态数据不太方便还需要写schema
【修改】放开page组件的静态数据配置，在saas重写了pageData的tpl，做了隐藏配置项的处理

• Extract the common logic for the page component's static data into a new schema template pageData in common.tsx (link)
• Replace the commented out code for the combo-container schema template in Page.tsx with a call to getSchemaTpl('pageData') to use the new template (link)
