Add custom page template for composable products, bump to v1.3.2

- Custom WooCommerce template with compact header + full-width selector
- Twig layout template (single-product-composable.html.twig) + PHP loader
- Body class 'single-product-composable' for CSS scoping
- Renamed *.twig to *.html.twig (proper naming convention)
- Refreshed .pot with accurate file refs, merged all .po files
