feat(extract): normaliser ghs_injustifie en 0/1 (P2)

Qwen renvoie typiquement le libellé complet `0 SE 1 2 3 4 ATU FFM FSD`
dans le champ ghs_injustifie alors qu'une seule valeur 0/1 est attendue.
Ajout de `pipeline.checkboxes.parse_ghs_injustifie` qui extrait le
premier chiffre 0/1 via regex, ou "" si illisible.

Post-traitement appliqué à chaque extraction recueil et aux 18 JSONs
V2 existants (10 fichiers corrigés en place — les 8 autres avaient
déjà ghs_injustifie absent ou vide).

Note sur les 7 cases SE1-4/ATU/FFM/FSD : zones trop petites pour être
calibrées à l'œil et aucun cas positif (`ghs_injustifie=1`) dans
l'échantillon 2018 pour valider visuellement. La détection est en
placeholder, à recalibrer sur un cas positif réel.
