feat: Permettre à l'enseignant de rédiger avec un éditeur riche et joindre des fichiers
Les enseignants avaient besoin de consignes plus claires pour les élèves : le champ description en texte brut ne permettait ni mise en forme ni partage de documents. Cette limitation obligeait à décrire verbalement les ressources au lieu de les joindre directement. L'éditeur WYSIWYG (TipTap) remplace le textarea avec gras, italique, listes et liens. Le contenu HTML est sanitisé côté backend via symfony/html-sanitizer pour prévenir les injections XSS. Les pièces jointes (PDF, JPEG, PNG, max 10 Mo) sont uploadées via une API dédiée avec validation MIME côté domaine et protection path-traversal sur le téléchargement. Les descriptions en texte brut existantes restent lisibles sans migration de données.
