feat(client): 登录历史下拉、macOS 兼容修复、UI 优化

- 替换 flutter_secure_storage 为 shared_preferences，解决 macOS Keychain 签名报错 - 登录页门店编号/用户名支持历史下拉（最多5条，LRU 淘汰），使用 Overlay + CompositedTransformFollower 实现浮层 - logout 仅删除 auth token，保留登录历史 - AppShell 时钟抽为独立 _ClockWidget，避免每秒 setState 导致 TabBarView 叠影 - ShellRoute 子路由改用 NoTransitionPage，消除切换页面时的过渡动画叠影 - 新增 auth_state_test、auth_repository_test、login_screen_test 共 14 个单元/Widget 测试 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
