feat(web): show multi-day calendar events on every day they span

TimelineItemView wraps a TimelineItem with a per-render-day
MultiDayVariant (starts/ends/spans/none). HandleTimeline's bucketing now
places a multi-day event into both TodayItems and TomorrowItems when it
touches both, instead of only the list matching its start day.
