- 恢复时除了 GetUserDataApi 再拉一次 GetUserPreviewApi：服务器说 isLogin 为 true 就把这次会话当已登录，_gameLogin 落地，票据与风险页按「登录后 60 秒冷却」计时 （loginDateTime 取恢复当下），不必再发一次 UserLoginApi - GetUserPreviewApi 的响应里没有 loginId，而 UpsertUserAll 要拿它当 playlogId， 所以导出连接信息时把本机的 loginId 一起带过去，恢复端优先用这个值， 拉不到才退回 preview 里的字段（多半是 0） - 只有 Cookie、preview 拉不到、或服务器说没在登录中时仍按只读处理， 提示横幅与 SnackBar 文案区分「可写」和「只能读」两种恢复结果 - HomePage 的恢复入口收成 restored: SessionRestoreResult?，把 preview 与 userData 一起当种子，省掉两次重复请求
