feat(combat): refonte UI — tracker v14, handicap III, malus d'attaque, checkbox

- combat-tracker.hbs + fight.mjs : alignés sur le CSS core v14 (header/tracker/footer, boutons <button>), attitudes/couleurs PJ-PNJ conservées, menu contextuel combatant réparé
- less/combat.less (nouveau) : styles custom tracker + footer sticky des dialogues
- handicap des 3 dialogues de jet étendu jusqu'à III
- dialogue d'attaque : champ « Malus temporaires » (malus sur les jets)
- checkbox/radio : flex: 0 0 auto global (fin des icônes étirées — ex. « Deuxième action » 228px → 24px)
- TEST_COMBAT.md : plan de test combat rejouable (S1-S8, tout PASS)
