fix: Add SPA mounting point for full mode

Problem: Customer SPA not loading in 'full' mode
Root Cause: In full mode, SPA loads on WooCommerce pages without shortcodes, so there's no #woonoow-customer-app div for React to mount to

Solution: Inject mounting point div when in full mode via woocommerce_before_main_content hook

Changes:
- Added inject_spa_mount_point() method
- Hooks into woocommerce_before_main_content when in full mode
- Only injects if mount point doesn't exist from shortcode

Result:
✅ Full mode now has mounting point on WooCommerce pages
✅ Shortcode mode still works with shortcode-provided divs
✅ Customer SPA can now initialize properly
