PostService は何のnamespaceにもおいてないですか？

はい、どこにもおいていない状況になります

ではエラーの通りですね。 namespaceまわりをもう少ししっかり見ると見えてくると思います。 https://www.php.net/manual/ja/language.namespaces.php

config/app.phpファイルのaliasesの最後のほうで、'UserService'になっていますが'PostService'とすべきではないでしょうか？ただ、他の方も言われているように、PostServiceクラスのcheck_permissionメソッドでやろうとしているような「認可」は、サービスよりも、ポリシーを使う場面かなと思います。
