feat: D30 combat effects, spell tiers, small damage removal, token HUD luck/grit

- Replace Knockback with Internal Injury on D30 (5, 10, 15); remove Shield Bash from D30 counter-attacks
- Eliminate small weapon damage: keep only medium damage labelled Damage in sheets, rolls, and chat
- D30 bonus dice (20, 27, 30) auto-resolved before grit/luck/shield decisions; choice dialogs for special strikes
- D30 combat effects: bleeding wounds, damage ×2/×3 before DR, DR ×2/×3 with component picker dialog
- Add hp.wounds to monster schema for bleeding support
- Show Save against spell? checkbox for all save rolls (not just magic users)
- Fix mulligan restart: persistent D30 process flags prevent double-application and allow both sides to react
- For Dice So Nice, show main roll animation before explosion dice for correct ordering
- Spell tier selection: force Standard/Overpowered choice at cast time, tier-specific aether cost, only chosen damage button shown
- Add +1/−1 luck and grit controls to Token HUD
- Fix inconsistent indentation, remove duplicate i18n key, remove unused includesShield return
