Refactor: Java-Klassen aus Services entfernt + .gitignore aus Repo
shares.py, zfs_runner.py: SharesManager/ZFSRunner → Modul-Funktionen Backward-compat Shims erhalten (zfs_runner/share_manager bleiben nutzbar) system_users.py, auth.py.bak: ungenutzte Dateien gelöscht .gitignore: aus Repo entfernt (enthält interne Pfade/Infos) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
