Verbessere OAuth-Unterstützung für m040tbaraspi001.de040.corpintra.net

- Füge dynamische Erkennung und Konfiguration von Hostnamen hinzu
- Erweitere Caddy-Konfiguration für m040tbaraspi001.de040.corpintra.net
- Konfiguriere OAuth mit expliziter NEXT_PUBLIC_OAUTH_CALLBACK_URL
- Passe Deployment-Skripte für Unternehmens-Hostname an
- Füge verbesserte Logging und Validierung für OAuth-Callbacks hinzu
- Füge ALLOWED_CALLBACK_HOSTS für Hostname-Validierung hinzu
