Answer 1

You can try a relative path
if (Yii::$app->user->isGuest) {
$menuItems[] = ['label' => 'Signup', 'url' => ['/site/signup']];
$menuItems[] = ['label' =>'Login','url' =>'../../../backend/site/login'];
} else {
add this in common/config/main.php
under the section components
'components' => [
.....
'urlManager' => [
'class' => 'yii\web\UrlManager',
'enablePrettyUrl' => false,
'showScriptName' => true,
],
.......

Answer 2

add to section components after urlManager in frontend/config/main.php
'urlManagerBackend' => [
'class' => 'yii\web\UrlManager',
'baseUrl' => 'http://backend.site.local',
'hostInfo' => 'http://backend.site.local',
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false,
],
in frontend/views/layout
add something like this
$menuItems = [
['label' => 'Home', 'url' => ['/site/index']],
['label' => 'Admin panel', 'url' => Yii::$app->urlManagerBackend->createUrl([''])],
];
