feat: add a title icon to every labelled card

Add card.ICON and a card.title helper that draws the glyph in the
highlight colour before the label, at the label's own size. The eight
labelled cards use it, in both the fit_unit width measurement and the
draw, so the icon cannot overrun a narrow cell. Clock (no label) and
weather (condition glyph already) are unchanged, and the no-data notice
titles stay text-only.

Codepoints were chosen against a rendered contact sheet, not fontconfig
alone, since a wrong codepoint draws a plausible neighbour.
