fix: persist CraftingTab sub-tab selection across tab navigation

- Add activeCraftingSubTab state + setActiveCraftingSubTab action to
  craftingStore (persisted to localStorage via zustand persist middleware)
- Add CraftingAttunement type to craftingStore.types and re-export from
  stores/index.ts barrel
- Update CraftingTab.tsx to read/write active sub-tab from store instead
  of local useState, so selection survives component remount
- Add default 'fabricator' value in craft-initial-state.ts
