Shopping cart update (APPS-779 -> 782)

[Fabtron]

What's new?

As base for some new UI adjustements the shopping cart including classes associated with the cart are converted and migrated to kotlin. In this process some refactorings were done.

The Ui were refactored so that we can now display discounts, deposits and other stuff more distinct in the shopping cart instead of displaying on big discount item showing the total amount.

The following changes have been made:

Apps-781 -> coupons can now be activated and deactivated on the coupons details page. The coupons are not displayed as part of the cart anymore and can only be added/deactivated via the details screen.
Apps-779 -> discount referring to the whole card are now display as seperate single item.
Apps-780 / Apps-782- > discounts referring to a product are now displayed below it if all the required details. If multiply discounts are added, they will bne displayd as a list below the product.
Apps-806 -> the give away item type and all the referring logic has been removed.

The changes and the ui have been rewritten in compose so the old recycler view accountable for the cart has been removed and should be replaced with the new composable screen.
