Updates the `createBackorderConfirmation` API call to dynamically specify whether to create a backorder (reliquat) or not.
Introduces a `toBackorder` parameter, enabling the API to handle both "with backorder" and "without backorder" scenarios based on user selection. This centralizes the backorder status setting within a single API call.
Additionally, adds loading indicators to the backorder dialog buttons for improved user feedback during the confirmation process.
Corrects API endpoints for creating, processing with, and processing without backorder confirmations.
Adds a new `isBackorder` getter to stock picking records for identifying backordered items, and improves the robustness of the `isDone` getter.
Integrates backorder detection into the reception validation process, prompting a dedicated confirmation dialog when a backorder is present.
Introduces new state management and methods (`withBackorder`, `withoutBackorder`) in the reception details model to handle the backorder confirmation logic.
Enhances the primary button component with a `backgroundColor` property for greater customization.
