🔧 Fix: Last Trip sensors staying Unavailable

The Last Trip Distance and Last Trip Efficiency sensors could stay Unavailable even after completing a drive — a trip was never recorded. Trip detection now works reliably: it's driven directly by the car's power mode on each update, so a trip is opened when you start driving and closed when you park (independent of the vehicle-start message timing). This also makes it robust to Home Assistant restarts mid-drive and to installing the feature mid-drive.

Efficiency Since Last Charge was unaffected and continues to work.
