refactor: 个人自用，移除登录与云同步全链路

站点只给本人用，云乐坊 SSO 授权、收藏/历史云同步、获客归因和账号切换记账都没有收益，却被登录状态检查和同步失败提示持续打扰。

- 删除 useYunlefunAuth / yunlefunAuth / yunlefunSsoConfig / yunlefunAuth 适配器、useUserDataSync / userDataSync / userData 适配器、三个 client 插件与 /auth/callback 回调页
- 抽出 adapters/cloudbase.ts，让「反馈一下」和匿名筛选信号不再依赖登录态；cook-feedback 云函数保留
- 删除 cook-user-data 云函数与 cook_user_data 权限规则，移除 @yunlefun/sso 依赖
- 「我的」页删掉登录按钮、账号卡、四个统计格和退出登录；「关于」页删掉项目作者、致谢名单和上游宣传链接
- 本地收藏/历史与导出导入保留，删除同步专用的 lastUid 记账
