Les entités Doctrine déclaraient déjà onDelete: CASCADE pour ces deux relations, mais les contraintes correspondantes étaient absentes en base. Conséquence : la suppression d'un composant pouvait laisser des documents ou des links machine orphelins. La migration nettoie les orphelins existants (avec trace dans audit_logs) puis ajoute les deux FK.
