feat(tesla): charging widget + in-car From pill + hide vehicle picker

- ChargingWidget: green topbar pill with live kW + battery + minutes-to-target,
  shown only when state.chargingState === 'Charging'. Animated bolt icon.
- Vehicle picker chip is hidden whenever Tesla is connected (anywhere, not
  just in-car) — we already know the car from vehicle_config.
- When in-car AND Tesla connected, the From input collapses to a static
  pill with a Tesla badge so the driver doesn't have to type on the touch
  keyboard. Destination input remains editable.
