 * Sous-ressource API (ERP-57, spec § 4.5) :

 *    (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).
