The groupedSchedule useMemo used slice(0, 2000) to limit events. With daily
medications having start dates far in the past, thousands of past events would
fill all 2000 slots, pushing today and future events completely out of the
display. This caused the past schedule to only show weekly medications (fewer
events) while daily medications appeared missing.
Replace the fixed count limit with a time-based window: only past events
within the scheduleDays window (30/90/180 days) are included. All today and
future events are always included regardless.
Coverage calculations are not affected as they use schedule.events directly.
