Add InPost Pay integration to admin templates

- Created a new template for the cart rule form with custom label, switch, and choice widgets.
- Implemented the InPost Pay block in the order details template for displaying delivery method, APM, and VAT invoice request.
- Added legacy support for the order details template to maintain compatibility with older PrestaShop versions.
