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.

+**Factory interfaces for PSR-7 HTTP Message.**
+
+## Obsolete
+
+The PHP-HTTP factories have become obsolete with the [PSR-17](https://www.php-fig.org/psr/psr-17/) factories standard.
+All major HTTP client implementors provide [PSR-17 factories](https://packagist.org/packages/psr/http-factory).
+
+This package will remain available for the time being to not break legacy code, but we encourage everybody to move to PSR-17.
+
+## Install
+
+Via Composer
+
+``` bash
+$ composer require php-http/message-factory
+```
