feat: full reroll includes D30 + shows dice breakdown in chat

- Remove forceNoD30 from rerollConfiguredRoll so mulligan
  rerolls the D30 along with the d20 and modifier
- Reset defenseD30Processed/attackD30Processed after mulligan
  so the new D30's effects (bonus dice, specials) are applied
- Render reroll dice breakdown (diceResults + D30 result) as
  inline HTML in the reaction chat message using existing
  CSS classes so players see what was rolled
