feat(desktop-client): suppress native menu bar on Windows/Linux and support phone number login

- Add suppressNativeWindowMenu() to hide native menu bar on all windows (Win/Linux only)
- Set autoHideMenuBar: true on BrowserWindow creation as belt-and-suspenders
- Import Menu from electron/main to support menu suppression
- Login form: rename field from email to identifier, support phone number input
- Migrate saved credential key from geo_rankly_saved_email to geo_rankly_saved_identifier with fallback
- Update login error message: "邮箱或密码错误" → "账号或密码错误"
- Remove unset ELECTRON_RUN_AS_NODE from dev script (not needed on Windows)
