Pull Request Overview

This PR implements a new parameter clearing mechanism to remember driver distraction state across system restarts when ignition is toggled on. This addresses the issue where driver distraction warnings were lost when restart_needed toggles were flipped.

• Adds CLEAR_ON_IGNITION_ON parameter type to selectively clear certain parameters when ignition turns on
• Implements ignition state tracking in the manager to trigger parameter clearing when ignition transitions from off to on
• Modifies driver monitoring to persist distraction state using the new parameter clearing behavior
