"""Tests des conditions combinées ET/OU (2.4).

Un nœud Condition peut porter plusieurs clauses (cond_clauses, JSON) combinées
par cond_combinator ('et'/'ou'), en plus de sa clause "historique" unique
(cond_definition_id/cond_field/...). Un nœud sans cond_clauses doit garder
EXACTEMENT son comportement d'avant (une seule comparaison) — c'est ce que
vérifient les tests de non-régression ci-dessous, en plus des tests dédiés
à la nouvelle fonctionnalité.
