i18n: draw naming-grid cells through Strings()

The name-entry keyboard drew each cell literally, so the case-switch labels
("lower case" / "UPPER CASE") and the "ED" confirm cell could not be
localized. Wrapping the draw in Strings() makes them translatable; the grid
data keeps the original strings, so the case-switch detection is unaffected.
Behavior-neutral for the base game (Strings identity without a catalog).
