Size the About logo to the card, not the card to the logo

At 72dp the launcher mark set the card's height on its own, towering over
the two text lines beside it and over the 40dp category chips on the rows
below. 56dp puts it at roughly the height of its own text, a step above the
row chips — still the block's anchor, no longer its outlier.

The mark is a vector, so this is purely a layout size; the 1.5x launcher-mask
overscan now lives in a constant rather than a second hardcoded number, so it
holds at whatever size the chip takes.
