fix(chat): size the popups from their rows, not the rows from a guess

An ImGui popup does not grow for draw-list content, so both new popups carried a
fixed minimum width -- and German outran it within a day. The menu clipped
Schnellauswahl and Chat ausblenden mid-word; the channel picker would have done
the same to Freie Gesellschaft on a narrow theme font.

PopupRow gets a CalcWidth that measures label plus icon plus padding under the
faces that will draw them, and both popups take the widest visible entry as
their width. Locale-proof by construction: whatever language writes the longest
string sets the size.
