fix: licensing table creation, consistent meta keys, checkout virtual detection

1. License table auto-creation:
   - Added ensure_tables() check on plugins_loaded
   - Tables created automatically if missing

2. Consistent licensing meta keys:
   - ProductsController now uses _woonoow_licensing_enabled
   - Matches LicensingModule and LicenseManager

3. Checkout virtual-only detection:
   - Added needs_shipping to Cart interface
   - Checkout uses cart.needs_shipping from WooCommerce API
   - Fallback to item-level virtual/downloadable check

4. Login redirect for logged-in users added previously
