fix: Elemental Mana Capacity disciplines now increase element capacity

- Add optional baseMax field to ElementState to track prestige-derived max separately from bonuses
- Add computeElementMaxWithBonuses action to manaStore that computes max = baseMax + per-element bonus
- Apply per-element cap bonuses from disciplines and equipment in game tick (elementCap_* keys)
- Fix resetMana to use correct prestige key (elementalAttune instead of nonexistent elemMax)
- Add store migration (v1->v2) to populate baseMax for existing saved games
- Extract pact ritual processing to pipelines/pact-ritual.ts
- Extract element cap bonus utilities to utils/element-cap-bonus.ts
- Fix inline element types in crafting-fabricator.ts
- Update test fixtures to include baseMax in element literals

Fixes #185
