Feat: Automate driver selection during FFU deployment

Adds a `DriverMapping.json` file to automate driver injection during image deployment. Driver download tasks now generate or update this mapping file with the relative path for each successfully downloaded driver package. The deployment script now uses this file to automatically detect and select the correct drivers for the target hardware, removing the need for manual selection. The manual driver selection prompt is retained as a fallback.
