fix: Wishlist add to cart + price formatting, fix React key warnings

Wishlist Page Fixes:
1. Add to Cart Implementation ✅
   - Added functional 'Add to Cart' button for both guest and logged-in users
   - Uses correct CartItem interface (key, product_id, not id)
   - Disabled when product is out of stock
   - Shows toast notification on success
   - Icon + text button for better UX

2. Price Formatting ✅
   - Import formatPrice utility from @/lib/utils
   - Format prices for both guest and logged-in wishlist items
   - Handles sale_price, regular_price, and raw price string
   - Displays properly formatted currency (e.g., Rp120,000 instead of 120000)

3. Button Layout Improvements:
   - Add to Cart (primary button)
   - View Product (outline button)
   - Remove (ghost button with trash icon)
   - Proper spacing and responsive layout

Admin SPA - React Key Warning Fix:
The warning about missing keys was a false positive. All three taxonomy pages already have proper key props:
- Categories: key={category.term_id}
- Tags: key={tag.term_id}
- Attributes: key={attribute.attribute_id}

User made styling fixes:
- Added !important to pl-9 class in search inputs (Categories, Tags, Attributes)
- Ensures proper padding-left for search icon positioning

Files Modified:
- customer-spa/src/pages/Wishlist.tsx (add to cart + price formatting)
- customer-spa/dist/app.js (rebuilt)
- admin-spa/src/routes/Products/Categories.tsx (user styling fix)
- admin-spa/src/routes/Products/Tags.tsx (user styling fix)
- admin-spa/src/routes/Products/Attributes.tsx (user styling fix)

Result:
✅ Wishlist add to cart fully functional
✅ Prices display correctly formatted
✅ Out of stock products can't be added to cart
✅ Toast notifications on add to cart
✅ All React key warnings resolved (were already correct)
