One card per run, newest first, from GET /api/review-classifier/runs: repo,
PR, head commit, trigger, when, how long, how many classifications and the
outcome as a badge. A card opens to the try-out's result table, the overall
verdict, the reason and the posted review's link. TryOutResult takes the
answer it shows rather than a whole try-out result, and its styles move to
their own file.
