feat: show only active vehicles on tracking map

Filter vehicles to status === 'ACTIVE':
- Map markers: only active vehicles displayed
- Vehicle dropdown: only active vehicles selectable
- All vehicles list: renamed to "Active Vehicles (count)"
- All use activeVehicles useMemo computed from vehiclesWithGPS

Inactive vehicles (maintenance, idle, etc.) hidden from tracking view.
