fix: Detect shortcode on WooCommerce Shop page correctly

Problem: Customer SPA not loading on Shop page despite having [woonoow_shop] shortcode
Root Cause: WooCommerce Shop page is an archive page - when visiting /shop/, WordPress sets $post to the first product in the loop, not the Shop page itself. So shortcode check was checking product content instead of Shop page content.

Solution: Add special handling for is_shop() - get Shop page content directly using woocommerce_shop_page_id option and check for shortcode there.

Changes:
- Check is_shop() first before checking $post content
- Get Shop page via get_option('woocommerce_shop_page_id')
- Check shortcode on actual Shop page content
- Falls back to regular $post check for other pages

Result:
✅ Shop page shortcode detection now works correctly
✅ Customer SPA will load on Shop page with [woonoow_shop] shortcode
✅ Other WooCommerce pages (Cart, Checkout, Account) still work
