The To do tab now lists only quizzes you've started and not finished;
untouched ones stay under All. Quiz times show hours and days
(3h 20m, 2d 4h) instead of ever-growing minutes, and 59.96s no longer
prints as "60.0s".

The All tab is now a click-through of category cards — Books, Lectures &
Conversations, Other quizzes — each opening its books or years, then the
quizzes themselves. Only categories with quizzes get a card. The position
and tab live in the URL (?in=books&book=bg, ?tab=todo), so refresh, Back
and shared links keep your place. Book quizzes list in chapter order.
