 /**
  * A Composable that provides an adaptive list-detail layout for products.
  *
  * It uses [NavigableSupportingPaneScaffold] to handle different screen sizes and orientations.
  * In large screens or landscape mode, it can show the list and details (or categories) simultaneously.
  *
  * @param onAddProduct Callback invoked when the user chooses to add a new product.
  * @param onCreateCatalog Callback invoked with a list of product IDs to create a catalog.
  * @param onEditProduct Callback invoked when the user chooses to edit a specific product.
