2025-09a (Revision A Release vom 10.09.2025)

Dieses Update behebt Abstürze des Skripts create_cold_standby und verhindert Aufrufe der update/generate-config-Skripte aus einem Verzeichnis, das nicht das mailcow-Root ist.

Außerdem verbessert es die Erkennung und Behandlung des neu eingeführten IPv6-Controllers und erkennt jetzt korrekt Docker-Versionen größer 28 (weniger erforderliche daemon.json-Einstellungen).
