Improve driver injection logic and user feedback

Enhances the driver mapping logic to ensure JSON files with a single entry are handled correctly. The model matching is now more flexible, allowing for partial matches in either direction between the system's reported model and the mapping file.

Adds a user-facing message to indicate that the driver injection process may take a significant amount of time, preventing confusion about the script stalling.
