Enhances driver download error handling and logging across Dell and Lenovo driver tasks.

- Implements detailed failure tracking for driver downloads, capturing model names and statuses for failed attempts.
- Updates logging to provide clearer messages for both successful and failed downloads, improving traceability.
- Modifies the user interface to display comprehensive error messages when downloads fail, including a summary of failed models.
- Ensures that all exceptions during download and extraction processes are logged and thrown, preventing silent failures.
