- results page: when there are no tracks (quiz-only game), the recap was sitting
in the left column of a 2-col grid; now a single section is centered (2 columns
only when both tracks and recap exist)
- add a shadcn Tooltip component (@workspace/ui, via radix-ui) and replace native
browser title= tooltips: connection dot, back-office active toggle, and the
locked blindtest tiles (now aria-disabled so the tooltip still triggers)
