feat: 主页改为原生皮肤站界面

主页原先内嵌整个皮肤站网页，现在换成启动器自己的界面，数据全部走
接口：

- SkinSiteAccountCard：登录状态、玩家列表（头像由皮肤裁剪生成）、
  每日运势。
- SkinSiteNavCards：资源下载、玩家审核、Wiki、漏洞追踪、地图、个人
  资料的入口，点击后用系统浏览器打开。
- SkinSiteAnnouncements：拉取公告并按重要度与时间排序。
- SkinSiteDonationCard：捐款累计金额与人数。
- SkinSiteHome：把以上拼装成主页，并显示可复制的接入地址。
- API 层补充捐款与公告接口。

Index.vue 的 iframe 换成 SkinSiteHome。
