feat: 主页账号备份，并修好 B50 预览缩不小
账号备份（AccountBackupCard + AccountBackupService）： - 并发读 GetUserData/Extend/Option/Rating/Charge/Activity/MissionData + Character + Map（分页）+ KaleidxScope + 各 itemKind 的 GetUserItemApi， 汇成一个 JSON 字符串可复制到剪贴板。舞里程与总游玩数据本就在 userData 的 point/totalPoint/playCount 里。 - itemKind 15（KaleidxScopeKey）不列进回读清单：客户端 ExportUserItems 从不输出它，下行也没有读它的路径，钥匙实际是 userKaleidxScopeList[].isKeyFound。 - 全程只发 GetUser*Api，不碰 UpsertUserAllApi。 - 逐段容错：私服没实现某个接口时其余照样备出，失败段单独列出—— 「读到但是空的」和「没读到」在 userItemList 里按 kind 分开存，可区分。 - 取数与拼装分开，buildBackupDocument/encode 部分是纯函数，单测覆盖。 B50 预览：原因是 InteractiveViewer(constrained:false) 给孩子无界约束， FittedBox(fit: fitWidth) 在无界下根本不缩放，海报按 1762x1850 原尺寸铺开； 而 minScale 又算成 1.0，于是既巨大又缩不动。改为给一个 contain 尺寸的 有限盒子让 FittedBox 真正缩放，minScale 固定 1.0（这个版本没有 initialScale 可用）。RepaintBoundary 留在 FittedBox 内侧，绘制尺寸仍是 1762x1850，导出分辨率不受影响，并加了断言守住这点。
