feat: détection erreurs imprimante via IPP direct (Selphy CP1300)

- script_print.sh : après lp, polling CUPS + sondage IPP direct ipp://IP:631/ipp/print
  Détecte input-tray-missing / media-empty en ~3-6s sans attendre le timeout CUPS
- printer_service.py : ajout _get_printer_ip(), _query_ipp_direct()
  _get_printer_status() utilise IPP pour état/raisons/encre (source de vérité)
- Timeout porté à 120s côté Python, fallback lpstat conservé
