Merge branch 'master' of http://git.dd:3000/AppStd/EnvelopeGenerator

- Methode `logInOut` aktualisiert, um nach dem Logout zu `/login` zu navigieren.
- Methoden `login` und `logout` angepasst, um `#IsAuthenticated` basierend auf der Antwort zu aktualisieren.
- Sicherstellung, dass der Authentifizierungsstatus nach Login und Logout korrekt gesetzt wird.
