fix: properly defined parameters for the URL function

See merge request !55

- Updated the version of phpstan in `.phive/phars.xml` from `1.11.8` to `1.*` and fixed its
installed reference to `1.12.13`.
- Added `@phpstan-ignore-line` comment to ignore certain lines in `Checkout.php`. The ignored lines
are 'Delivery' in the function `getBody()` and checking `validateAddress` in the function
`isValid()`. These adjustments help to suppress any unnecessary lint warnings which phpstan may
raise.

New Events: onQuiqqerSimpleCheckoutBodyEnd + onQuiqqerSimpleCheckoutValidation

In the update.php modified to initialize erpAddressData with empty strings in case the values
obtained from $orderData are null.

In SimpleCheckout.js module, simplified setting `Checkout` attribute for Delivery, Shipping,
Payment, and Billing by looping through them in an array.

Added verification to ensure existence of certain steps before attempting to invoke methods on them
to prevent potential errors because of non-existence.

In the checkout template, add code to display delivery and Payment only if the corresponding data
exists.

In Checkout.php introduced logic to control the display of delivery, shipping, and billing
addresses sections.

In CheckoutPayment.php added conditions to check existence before validating delivery to prevent
potential errors.

Conditional checks and event firing mechanisms were introduced to validate the shipping service.
This significantly streamlines the code and makes it more resilient against potential errors.

See merge request !53

This commit implements minor refactoring changes in the SimpleCheckout.js file.

declarations for improved readability.
- Modified DOM manipulation logic to use data-name attribute instead of class name for element
selection, enhancing selection accuracy.
- Added data-name attribute set command to retain DOM element specific data when replacing HTML.
- Improvements in 'require' callbacks to use fat arrow function notation.
- Minor adjustments in formatting in methods dealing with Events and DOM manipulations.

fix: hide checkout details and payment container during processing

See merge request !51

In `SimpleCheckout.js`, an animation has been added to enhance the user experience while scrolling
to the payment container. On the other hand, in `Checkout.html`, the
`quiqqer-simple-checkout__scrollToPaymentContainer` class has been updated to initially set the
opacity to 0 to make the animation smoother.

This commit hides the elements '.quiqqer-simple-checkout-orderDetails' and
'.quiqqer-simple-checkout__scrollToPaymentContainer' in 'SimpleCheckout.js' during processing. When
the element with '.quiqqer-order-step-processing' class is present, the mentioned elements are set
to 'display: none', preventing them from being viewed during order processing. The same logic
applies when the order is successful, ensuring a cleaner interface during these steps.

Only the address is then displayed. The address cannot be changed/edited by the user.

Coupons were incompatible with simple checkout. Since coupons insert text articles into the order.
However, text articles destroyed the basket.
