librelad 0b27ed1072 refactor(desudo): funnel backup-engine privilege drop through runBackupOp
The borg/restic/kopia engines all dropped to the dedicated backup user
via scattered 'sudo -E -u $docker_install_user'. Centralize that into a
single runBackupOp helper so the backup subsystem has one audit point and
the scoped sudoers needs only the (dockerinstall) drop rule.

Also:
- owncloud config heredoc tees -> runSystem (container-UID file)
- webui_display_logins: fix the broken 'command -v sudo sqlite3' guard
  to 'command -v sqlite3' (body already runs sqlite3 via runInstallOp)
