 *  - filtrage des cles sensibles (defense-in-depth par rapport a #[AuditIgnore]) ;
 *  - utilisation du username courant ou "system" en CLI ;
 *  - captation IP + request_id si requete HTTP presente ;
 *  - generation d'un UUID v7 (tri chronologique implicite en PK).
 *
 * Aucune BDD : la connexion DBAL est mockee pour capturer l'insert.
