The expression return $this->goHome() returns the type yii\web\Response which is incompatible with the documented return type string.

The expression return $this->goBack() returns the type yii\web\Response which is incompatible with the documented return type string.

        } else {
            return $this->render('login', [

The method logout() does not exist on null.

        return $this->goHome();

The expression return $this->goHome() returns the type yii\web\Response which is incompatible with the documented return type string.

    /**
     * @param string $action
     * @param bool $saveOldData

     */
    protected function logUserAction($action, $saveOldData = false, $saveNewData = false)
    {
        $user = new User(Yii::$app->user->identity);

It seems like Yii::app->user->identity can also be of type yii\web\IdentityInterface; however, parameter $config of backend\models\User::__construct() does only seem to accept array, maybe add an additional type check?

        Log::find()
            ->createLogEntity($user, $action, $saveOldData, $saveNewData)
            ->save();
    }
