/**
 * Editeur plein ecran d'une fiche de personnage (PJ).
 * Refonte 2026-04-30 : remplace le markdown libre par un formulaire dynamique
 * pilote par le characterTemplate du GameSystem associe a la campagne.
 *
 * Comportements :
 *  - Si la campagne n'a pas de GameSystem ou si son template est vide, affiche
 *    uniquement les champs universels (nom, portrait, header).
 *  - Le picker d'images dedie portrait/header est hors scope MVP — pour l'instant
 *    saisie manuelle d'IDs d'images.
