Dashboard: fix dial sizing so ODO never gets clipped, no giant gap

The dial Box now claims all leftover vertical space (weight 1, fill=true)
and sizes the gauge to fit both available width and height. On phones it
stays a near-square (ratio 1.05); on tablets it becomes a wide-arc
car-dash speedo (ratio 2.0) so the wide screen is actually used. The
weighted bottom Spacer between action buttons and ODO is gone, so the
footer sits where it belongs without a giant mid-dashboard hole.

Bumps version to 0.3.2-p6preview13.
