/**
 * NIS2 Agile — DDL idempotente Riesame di Direzione (ISO 27001 §9.3, mig.056).
 * ----------------------------------------------------------------------------
 * Crea (se mancanti) le tabelle del Modulo B "Riesame di Direzione":
 *   - management_reviews            (il verbale: input aggregati congelati + esiti)
 *   - management_review_decisions   (decisioni/output → owner ruolo, scadenza, CAPA)
 *
 * NESSUN dato di sistema: i riesami sono per-org (creati dall'utente).
 *
 * Idempotente: CREATE TABLE IF NOT EXISTS (re-eseguibile senza errore; in caso
 * di tabella già presente ignora gli errno 1050/1061). Allineato a
 * docs/sql/056_management_reviews.sql.
 *
 * Uso (dentro il container app, o sull'host con la stessa connessione PDO):
 *   docker exec nis2-app php /var/www/nis2-agile/application/cli/seed_management_reviews.php
