Sign in with Klarna on SAP Commerce Cloud

The ''Sign in with Klarna'' feature is included in the '''Klarna Add-on''', so no separate installation is necessary. However, a clean build of the package and an update of the database schema are required to generate new data models and data transfer objects (DTOs).
