Fix formule de dés : 2d8 de base (règles Célestopol)

Correction majeure de la mécanique de jet selon les règles :

- Formule : 2d8 + Spécialisation + modificateurs (blessures/aspect/manual)
  (vs. ancienne formule erronée : Nd6 pool variable)
- Dé de la Lune : 1d8 narratif optionnel (résultat 1-8 → Triomphe /
  Brio / Contrecoup / Catastrophe) — pas un bonus numérique
- Destin : disponible uniquement jauge pleine (lvl=8), donne 3d8,
  vide la jauge entière après usage
- system.mjs : MOON_DIE_FACES (tableau 1-8) + MOON_RESULT_TYPES
- roll.mjs : logique complète réécrite (2d8, lune séparée, destin reset)
- character/npc.mjs : prefs.rollMoonDie + destGaugeFull
- roll-dialog.hbs : sans grille lune, checkbox dé lune, destin conditionnel
- chat-message.hbs : résultat dé lune narratif (phase + type + desc),
  dés .d8, suppression moonSymbol/moonBonus header
- roll.less : .form-moon-row, .moon-die-result avec couleurs Triomphe/
  Brio/Contrecoup/Catastrophe
- lang/fr.json : Moon.triomphe/brio/contrecoup/catastrophe + Full descs,
  Roll.rollMoonDie/destGaugeFull/destGaugeEmpty/baseDice
