feat: put the weather card under the clock, scale its type to width

Placement is column 1 row 2, directly beneath the clock, which drops to
a single-row cell to make room.

The card's type now scales off the cell WIDTH rather than its height.
Scaling off height meant the text shrank every time the cell got
shorter, and beside the clock's numerals the card read as a whisper.
Width is the stable dimension for this layout and is what constrains the
text anyway, since the stat rows run edge to edge.

Verified against the live dashboard, not only the offscreen render: the
two disagreed about type size precisely because the offscreen harness
was cropped to the card and never showed it next to the clock.
