 * (RG-1.06/07/08). Un email de facturation est obligatoire ssi isBilling
 * (RG-1.11). Au moins un site doit etre rattache (RG-1.10, Assert\Count). Ces
 * regles sont portees par des Assert\Callback (cf. validateProspectExclusivity /
 * validateBillingEmailPresence, ERP-76) qui remontent une 422 avant la base ;
 * les CHECK Postgres (chk_client_address_prospect_exclusive /

 * Relations M2M :
 *  - sites : SiteInterface (module Sites) via resolve_target_entities
 *  - contacts : ClientContact (meme module)
 *  - categories : CategoryInterface (module Catalog) via resolve_target_entities
 *    — limitees aux types SECTEUR/AUTRE (RG-1.29, validateCategoryTypes, ERP-76)
 *
 * Audite (#[Auditable]) + Timestampable/Blamable.
 *
 * Sous-ressource API (ERP-57, spec § 4.5) :
 *  - POST /api/clients/{clientId}/addresses : creation rattachee au client parent
 *    (Link toProperty 'client'), security commercial.clients.manage.
 *  - PATCH / DELETE /api/client_addresses/{id} : security commercial.clients.manage.
 *  - GET /api/client_addresses/{id} : lecture unitaire (security view) — la
 *    lecture courante reste via le parent. Pas de GET collection autonome.
 * Tout passe par le ClientAddressProcessor (normalisation RG-1.21 billingEmail).
