Subject: [PATCH] fix: use fixed timestamps in HistoryPreview test to prevent
 Windows sort flakiness

Date.now() can tick between sequential calls on Windows, producing
different millisecond values per mock task.  useGroupedTasks sorts
newest-first, so slightly increasing timestamps reversed the expected
order, causing task-1 to fall outside the first 4 displayed groups.

Replaced Date.now() with deterministic, descending timestamps so the
sort always yields task-1 through task-4 regardless of platform.
