Fügt Unterstützung für die neue nuscore API hinzu. Aktualisiert die Backend-Routen zur Verarbeitung von Anfragen an die nuscore API und integriert die neuen Dialogkomponenten im Frontend. Ermöglicht das Erstellen lokaler Kopien von nuscore-Daten und verbessert die Benutzeroberfläche durch neue Schaltflächen und Dialoge. Entfernt veraltete Konsolenausgaben und optimiert die Logik zur PIN-Verwaltung.
