字体切全量、评论徽章优先级、友链自助申请卡片、友圈头像兜底

- 字体：zql 从 subset(776K) 切换到全量(1.2MB woff2)，subset 覆盖
  不足导致大量字回退系统字体，视觉不一致；全量一次加载彻底解决
- 评论徽章统一 comment-rendered 注入，优先级互斥：友链 > 友圈 >
  官职（后端 rank 字段），官方系统徽章（博主）独立显示
- 留言页新增友链自助申请入口卡片 + 弹窗表单（名称/链接/订阅/邮箱
  必填），提交进 api.200181.xyz 待审队列，审核结果邮件通知申请人
- 友圈头像：favicon 抓取失败时兜底第三方 favicon 服务
