fix(app): account-switch data residue + empty-albums pull-to-refresh
- 换账号数据残留（用户报告）：albumListProvider 非 autoDispose 且首页 IndexedStack 常驻——登出与登录成功两处显式 invalidate（任务库本就按账号 隔离键隔离，不受影响） - 空相册无法下拉刷新（用户报告）：空态原本直接 return EmptyState 无 RefreshIndicator——被拉进相册后无法手动刷新；空态改入可滚动容器承载 下拉刷新（保留新建入口） - 397/397 全绿、analyze 0 Co-Authored-By: Claude Code <noreply@anthropic.com>
