feat: 联系博主页对接博主介绍/社交动态列表，下线友链提交页

- contact.vue：博主介绍（intro 富文本）用 mp-html 完整配置渲染（domain/loading-img/
  tag-style/container-style/markdown，对齐 moments/文章详情）；社交信息改读
  authorConfig.social.items 动态列表（priority 排序、visible 过滤、未配置空态、
  不回退默认值），去 enabled 开关；收信日期改 formatTime 实时显示
- about.vue：社交入口判定改按社交项列表（存在可见且有内容即展示）
- 友链提交功能调整：submit-link 页面下线，mini-info/site-info 与提交开关
  （submissionEnabled）随插件端新结构对接
