/**
 * NIS2 Agile — Importer idempotente del registro Stakeholder (Epic C / C5.1).
 * ----------------------------------------------------------------------------
 * Crea (se mancanti) le tabelle del modulo Stakeholder (mig.051) e popola i dati
 * di SISTEMA: i 4 quadranti della matrice di Mendelow (range corretti, Q4 potere
 * 0-2) e i 30 tipi di stakeholder Stak.01-30 (6 Interni / 24 Esterni) dal seed
 * autoritativo application/data/nis2_framework_seed.json (chiave stakeholder_types,
 * generata dai file docs/simon/*.xlsx — codifica NON variabile).
 *
 * Idempotente: CREATE TABLE IF NOT EXISTS + INSERT ... ON DUPLICATE KEY UPDATE
 * sul PK `code` (nessuna trappola NULL-dedupe: il codice E' la chiave primaria).
 * Rilanciabile senza duplicare ne' rompere le FK. Sostituisce i runner usa-e-getta.
 *
 * NB: la matrice di Mendelow (potere/interesse) e' BUONA PRASSI, NON un obbligo
 * NIS2; l'obbligo e' GV.SC-02 (ruoli/responsabilita verso fornitori/clienti/partner).
 *
 * Uso (dentro il container app):
 *   docker exec nis2-app php /var/www/nis2-agile/application/cli/seed_stakeholders.php
 *
 * NB: solo CLI. DB API via PDO singleton (Database::getInstance()), TLS gestito
 * dalla config dell'app.
