Updated: Improved vehicle and refuel data handling on dashboard

Updated:
- DashboardController now fetches latest refuel record only for the default vehicle
- VehicleController - first created vehicle is now set as default automatically
- Refuel model - latest_one() now accepts vehicle_id instead of user_id
- Dashboard view - improved handling when no vehicles or refuel records exist
- CSS styles - adjusted dashboard layout and global action padding
