fix: 修复通知系统链接错误、标记已读失败及帖子404页渲染异常

- 修复 post_rejected 通知链接到帖子详情页（原来链接到 /studio/posts）
- 为 audit_approved/audit_rejected 通知添加链接到 /settings
- 通知已读标记改用 fetch keepalive 代替 sendBeacon，附带 CSRF token，避免页面跳转时请求丢失
- 修复 repository 层 id 列名应为 uid（BaseModel 定义 primarykey column:uid）
- 帖子404页添加 ExtraCSS 引入 posts.css，修复 SVG 图标无尺寸约束全屏渲染异常
