Feature: MacOS-Toggle + Raw-Editor im Samba Config-Tab

- Toggle 'Global MacOS Shares' setzt/entfernt fruit-Parameter automatisch
  (fruit:encoding=native, fruit:metadata=stream, fruit:zero_file_id=yes,
  fruit:nfs_aces=no) via net conf setparm
- Raw-Textarea zeigt alle globalen Parameter direkt editierbar (key = value)
- Tabellen-Ansicht durch Raw-Editor ersetzt
