fix: Guest wishlist now fetches and displays full product details

Problem: Guest wishlist showed only product IDs without any useful information
- No product name, image, or price
- Product links used ID instead of slug (broken routing)
- Completely useless user experience

Solution: Fetch full product details from API for guest wishlist
- Added useEffect to fetch products by IDs: /shop/products?include=123,456,789
- Display actual product data: name, image, price, stock status
- Use product slug for proper navigation: /product/{slug}
- Same rich experience as logged-in users

Implementation:
1. Added ProductData interface for type safety
2. Added guestProducts state and loadingGuest state
3. Fetch products when guest has wishlist items (productIds.size > 0)
4. Display full product cards with images, names, prices
5. Navigate using slug instead of ID
6. Remove from both localStorage and display list

Result:
✅ Guests see full product information (name, image, price)
✅ Product links work correctly (/product/product-slug)
✅ Can remove items from wishlist page
✅ Professional user experience matching logged-in users
✅ No more useless 'Product #123' placeholders

Files Modified:
- customer-spa/src/pages/Wishlist.tsx (fetch and display logic)
- customer-spa/dist/app.js (rebuilt)
