fix(workouts): order the list newest-first; show the year on past-year dates

The canonical picker re-sorts its output to startedAt ASC for its rollup callers, so the list route sliced the oldest page and recent workouts never surfaced on a long history — re-establish newest-first after the pick. And a workout from a previous year now shows its year so it is not read as this year's.
