librelad 43779a992b harden(desudo): backup engines (restic/kopia/borg) + crowdsec host helpers
- restic_install, crowdsec_update/verify_firewall/fix_priority: pure host
  ops (apt/cscli/nft/systemctl, /etc/crowdsec) -> runSystem.
- kopia_backup/borg_restore: ignore-file/target tee+chown+mkdir -> runFileOp/
  runFileWrite; kept the 'sudo -E -u dockerinstall' engine calls as-is —
  those already run as the unprivileged backup user (least-privilege; the
  scoped sudoers will permit (dockerinstall)).
