feat: Einführung von Umgebungsvariablen und Startskripten für die Backend-Anwendung

- Hinzufügen eines zentralen Skripts zum Laden von Umgebungsvariablen aus einer .env-Datei.
- Implementierung von Start- und Entwicklungs-Skripten in der package.json für eine vereinfachte Ausführung der Anwendung.
- Bereinigung und Entfernung nicht mehr benötigter Minigame-Modelle und -Services zur Verbesserung der Codebasis.
- Anpassungen an den Datenbankmodellen zur Unterstützung von neuen Assoziationen und zur Verbesserung der Lesbarkeit.
