removeAllSavedVehicles function

Deletes all saved vehicles from native platform storage.

This method removes ALL previously saved vehicle associations, effectively resetting the vehicle configuration to a clean state. After calling this method, automatic trip detection will be disabled until new vehicles are saved.

Behavior:

• Removes all saved vehicle devices from native storage
• Clears vehicle-based automatic trip detection rules
• Cannot be undone - all vehicle data is permanently deleted
• Does not affect currently active trips

Platform Communication:

• Method Channel: 'removeAllSavedVehicles'
• Parameters: None
• Side Effects: Clears native vehicle storage completely

Usage Example:

// Typically used with user confirmation
final confirmed = await showConfirmDialog('Delete all vehicles?');
if (confirmed) {
  removeAllSavedVehicles();
  print('All vehicles deleted - automatic detection disabled');
}

Important Considerations:

• Irreversible Action: All vehicle data is permanently lost
• Trip Detection Impact: Disables automatic trip start/end detection
• User Experience: Users will need to re-scan and save vehicles
• Use Sparingly: Consider removeSavedVehicle for selective removal

When to Use:

• Factory reset scenarios
• Troubleshooting trip detection issues
• User switching to completely different vehicles
• Clean slate setup for new users
• Resolving corrupted vehicle data

Alternative:

• Use removeSavedVehicle() to remove specific vehicles instead of all
