feat(content): 小程序「政策」tab→资讯中心(分类feed)

- 新增 pages/content(资讯中心)：类别分段tab(政策/资讯/技能/动态) + published列表；政策分类下提供「政策测评」入口(原测评页保留非tab)
- 新增 pages/content-detail(资讯详情：title/summary/body)
- utils/content.js：listContent(cat)/cachedContent/getContent(公开 /opc/content)
- app.config：tab 政策→资讯(pages/content)、注册 content/content-detail、policy 保留注册
- custom-tab-bar：政策→资讯
