fix: tests complets - onglets, message de tchat, scores bonus/malus

- Onglets item (Anomalie/Aspect/Attribut): correction tabGroups + data-group sur chaque <a> et <section>
- Onglets acteur (PJ/PNJ): tab.cssClass dans les templates pour l'état actif initial
- Message de tchat: alignement des noms de variables _getChatCardData <-> chat-message.hbs
  - actorName, actorImg, success/failure, diceResults, statLabel/skillLabel localisés
  - difficultyLabel et moonPhaseLabel localisés depuis SYSTEM
- Dialogue de jet (roll-dialog.hbs): correction noms variables + min/max modificateur
- lang/fr.json: ajout Roll.title, Roll.roll, clés Moon (minuscules), Difficulty (unknown/ardu)
- character.mjs: passage statLabel à CelestopolRoll.prompt()
- global.less: padding + overflow-y sur .tab pour contenu visible
- item-scores.hbs: passage system=system au partial + suppression garde isEditable
- Templates anomaly/aspect/attribute: passage system=system au partial item-scores
- chat-message.mjs: getHTML() → renderHTML() (dépréciation FVTT v13)
