Fix crafting tab crash, update attunement XP system

- Add missing EquipmentCraftingProgress interface to types.ts
- Fix CraftingTab to accept store prop like other tabs
- Update attunement XP calculation: 1 XP per 10 capacity used (min 1)
- Change XP requirements: 1000 for lv2, 2500 for lv3, doubling thereafter
- Grant Enchanter XP when enchantments are applied
- Add equipmentCraftingProgress to GameState and persist config
