整合小红书页面：内联扫码登录、用户主页、移除独立登录和内容浏览页

- 新增 XiaohongshuPage：顶部搜索栏、登录用户头像/ID、退出按钮
- 未登录时内联显示二维码，无需跳转独立登录页
- 点击笔记作者可打开用户主页 slide-over（复用 UserCard）
- 修复用户主页关注/粉丝/获赞数为零：选择器从 .data-area .data-item 改为 .user-interactions > div
- 修复用户头像选择器：img.user-image（img 本身带该 class）
- backend LoginStatus 新增 avatar/userId 字段，登录状态接口返回头像和用户 ID
- 删除 LoginPage、BrowserPage，侧边栏精简为小红书单入口
