Code-Vereinfachung: Redundanzen entfernen und Wiederverwendung verbessern

- log() Funktion in darktable_common.sh ausgelagert (war doppelt vorhanden)
- ssh_server() Hilfsfunktion für wiederholte SSH-Aufrufe mit konsistenten Optionen
- ssh_server() nutzen statt inline SSH-Befehle in darktable_sync.sh und darktable_wrapper.sh
- Reduzierung von SSH-Optionswiederbholungen (ConnectTimeout, BatchMode, Port)
