Rotating the phone into landscape while leveling used to leave a
portrait-shaped column of controls that needed scrolling to take in.
All three level-integration screens now branch on verticalSizeClass:
the bubble/vehicle status in the device screen and the full alignment
assistant (advice, readings, and wedge heights) lay out side-by-side
instead of stacked, sized to fit without scrolling.
The device screen also measures its actual available height via a
GeometryReader and feeds it to the level display so the bubble/vehicle
graphic scales to fill the landscape screen rather than being capped at
a fixed size, and the connection-status section moves to the bottom of
the list in landscape so it doesn't compete with the display for space.
