feat(ui): open the move history at the newest move; scale the landscape rack glyphs

The move table fills top to bottom, oldest first, so it used to open on the
opening moves — the least interesting end of a long game. Pin it to its last
row when it is shown (the portrait drawer and the landscape dock alike), once
per showing rather than on every arriving move, so a player reading back
through the journal is not yanked to the bottom by an opponent's move.

The landscape tray shares the narrow left panel, so its tiles — and with them
the cqw-sized glyphs — come out markedly smaller than the full-width portrait
tray. Scale the letter and Erudit's blank star up a quarter there; the point
value keeps its size (it reads fine small, and growing it would crowd the
letter on a tile that size).
