/**
 * Fixtures dev/test du module Commercial : ~14 clients de demonstration couvrant
 * l'ensemble des cas metier RG-1.xx du repertoire clients (M1) :
 *  - client basique ; dependant distributeur / courtier (RG-1.03) ;
 *  - reglement LCR avec 2 RIB (RG-1.13) ; reglement Cheque sans RIB ;
 *  - multi-adresses Prospect / Livraison / Facturation (RG-1.06/07/08/11) ;
 *  - prospect seul ; 3 contacts dont un avec telephone secondaire (RG-1.05/1.02) ;
 *  - client archive (RG-1.22) ; onglet Information complet ; multi-categories M2M.
 *
 * Resolution inter-modules conforme a la regle n°1 (pas d'import direct) :
 *  - categories resolues via le contrat Shared CategoryInterface
 *    (resolve_target_entities -> Category) ;
 *  - sites resolus via le contrat Shared SiteProviderInterface.
 *
 * Normalisation : les valeurs sont fournies BRUTES (casse libre, telephones
 * formates) et normalisees par ClientFieldNormalizer avant persist, exactement
 * comme le ferait le ClientProcessor via l'API (companyName UPPERCASE,
 * first/last Capitalize, telephones chiffres seuls, emails lowercase).
 *
 * Distributeur / courtier auto-references (RG-1.03) : les tiers referencables
 * (GSO distributeur, Cabinet Leonard courtier) sont crees AVANT les clients qui
 * les referencent ; un unique flush en fin de load ordonne correctement les
 * inserts auto-references.
 *
 * Idempotence : lookup par companyName normalise (coherent avec l'index unique
 * partiel uq_client_company_name_active). Un client deja present n'est pas
 * reconstruit (ses sous-collections ne sont pas redupliquees). Rejouable sans
 * doublon meme si le purger Doctrine est desactive.
 *
 * Audit / Blamable : persist hors contexte HTTP -> created_by / updated_by
 * restent null (« Systeme » cote front), c'est attendu. Les donnees respectent
 * les CHECK BDD ET les validators applicatifs (exclusivite Prospect, billingEmail
 * ssi facturation, aucune categorie de code DISTRIBUTEUR/COURTIER sur une adresse
 * — RG-1.29, ERP-78).
 *
 * Depend de CategoryFixtures (categories), SitesFixtures (sites) et
 * CommercialReferentialFixtures (referentiels comptables Bank / PaymentType).
 *
 * Portee : DONNEES DE DEMONSTRATION (dev uniquement). En environnement `test`,
 * la fixture ne charge rien : les tests seedent et nettoient leurs propres
 * clients et comptent sur une table `client` vierge — y injecter 14 clients de
 * demo casserait les comptages de liste et les cleanups. Meme garde-fou que
 * CategoryFixtures.
