refactor: Replace natural-regen disciplines with mana conversion speed disciplines

- Add conversionRate + sourceManaTypes fields to DisciplineDefinition
- Rewrite elemental-regen.ts: 8 base disciplines now convert raw→element
- Rewrite elemental-regen-advanced.ts: 6 composite/exotic disciplines with proper source recipes
- Update discipline-effects.ts: produce conversion entries instead of regen bonuses
- Update gameStore.ts tick: drain source mana types, add to target element
- Update discipline-slice.ts: gate activation on source mana type access
- Update discipline-math.ts: resolve mana type IDs to 'X mana' display names
- Update DisciplinesTab.tsx: show conversion info, source requirements, and lock state
- Update DisciplineDebugSection.tsx: pass elements to activate()
- Update effects.ts: remove regen_{element} merge (no longer produced)
