/**
 * NIS2 Agile — DDL idempotente Attività stakeholder (Epic C / C5.2a, mig.052).
 * ----------------------------------------------------------------------------
 * Crea (se mancanti) le tabelle del modulo Attività stakeholder ed estende
 * l'ENUM entity_type di review_schedule con 'stakeholder_activity' (calendario NIS2).
 * NESSUN dato di sistema: i questionari tipo sono per-org.
 *
 * Idempotente: CREATE TABLE IF NOT EXISTS + ALTER MODIFY (re-eseguibile senza
 * errore). Allineato a docs/sql/052_stakeholder_activities.sql.
 *
 * Uso (dentro il container app):
 *   docker exec nis2-app php /var/www/nis2-agile/application/cli/seed_stakeholder_activities.php
