test: fix leaderboard smoke test for gallery-default tab + sr-only label

Gallery is now the default tab, so the Leaderboard content is hidden on
load; click the Leaderboard tab before asserting. Scope the label
locator to the visible <p> since the Leaderboard widget also renders a
screen-reader-only <caption> with the same text (strict-mode 2-element
violation otherwise).
