chore: release v0.1.1.30

Erweitert die Backup- und Restore-Skripte um die Möglichkeit, Staging-Umgebungen zu unterstützen. Fügt die Option `-dest stage` hinzu, um spezifische Konfigurationen für Staging zu verwenden, einschließlich separater Docker-Compose-Dateien und Datenbankcontainer. Dokumentation aktualisiert, um manuelle Tests und Umgebungsvariablen für Staging zu reflektieren.
