Done. Next steps:
  1. Edit /etc/olive/config.json  (set tz, placement_note, threshold).
  2. Create the service user:      sudo useradd -r -g audio olive && sudo chown -R olive /var/lib/olive
  3. Start it:                     sudo systemctl enable --now olive-monitor
  4. Watch logs:                   journalctl -u olive-monitor -f
  5. Generate a report:            /opt/olive/.venv/bin/olive-report --config /etc/olive/config.json --out report.html
