feat(ela): 菜单全换 ElaMenu/ElaMenuBar(根治圆角露直角) + 登出功能

- TopBar: 4 主菜单/子菜单/切换器菜单 → ElaMenu, 菜单栏 → ElaMenuBar(自绘透明圆角弹窗+随主题);
  去掉 #appMenuBar 内联 QSS; Theme.cpp 删除 QMenuBar/QMenu QSS(否则 border-radius 仍露直角)
- 登出: 头像改可点击 QToolButton + ElaMenu「退出登录」→ logoutRequested 信号;
  main 接信号 → forgetSession() 清凭证 + QProcess 重启回登录页(撤销之前的 GEOPRO_FORCE_LOGIN 补丁)
