Depot: per-vehicle wagon number, model path, activation after removal

The number editor was pinned to the unit's first car, so every vehicle in a
multiple unit shared one number. Removing a vehicle only moved the highlight,
leaving the starting vehicle and the panels on the deleted one. Drops the tab
strip around the single configuration panel and shortens the consist row when
the thumbnails are small.
