构建环境镜像添加

- 文件管理器分页加载、排序偏好、桌面表头排序、移动端排序菜单、Ctrl/Cmd+F搜索、Esc 关闭搜索、鼠标右滑返回上级。
- 移动端同步状态页、同步统计卡片、同步任务/累计统计事件、同步页布局更新。
- Android 相册同步默认路径改为 DCIM/Camera，下载路径改用 external_path。
- Rust sync-core 更新：Android 日志依赖、AlbumUpload/AlbumDownload、MirrorWcf 统计修复、Linux FUSE镜像挂载与读写同步支持。

- 依赖更新：external_path、fl_chart、pdfrx 升级，并修了 pdfrx 新版本的deprecated API。
- 新增文件包括：sort_options.dart、sync_page_android.dart、sync_stats_card.dart、platform/fuse.rs、sync_engine/fuse.rs。
