fix: fabricator recipes now use correct elemental mana type

- fabricator-recipes.ts: add optional manaType param to canCraftRecipe for clarity
- FabricatorSubTab.tsx: read elemental mana from store based on recipe manaType instead of always using rawMana
- craftingStore.ts: add startFabricatorCrafting action that deducts correct mana type
- craftingStore.types.ts: add startFabricatorCrafting to CraftingActions interface
- crafting-fabricator.ts: new helper file to keep craftingStore.ts under 400 lines

Fixes #155
