Refactor scan model response variable assignment

Simplified the retrieval of config and engines by using a single variable, `scanModelResponse`, to improve code readability and maintainability. This change consolidates access to elements of `allScansModel.Scans[0]` into one clear reference point, making the code easier to understand and modify in the future.
