westfarn 783712972b Show in-progress multi-day events on the calendar (#33) ...

## Summary
Closes #32.
- Keep an event on Upcoming until its end date is over. If `end_time` is set, it drops off once that time passes on the end date, so an in-progress multi-day event stays visible.
- Render the Past tab from `past_events` instead of `future_events`.
- Show the start–end date range when the dates differ.

## Test plan
- [ ] Multi-day event that started yesterday and ends tomorrow appears under Upcoming
- [ ] Event whose end time has already passed appears under Past
- [ ] Future single-day event still appears under Upcoming
- [ ] Past tab lists finished events only
- [ ] `uv run python manage.py test schasite.tests.CalendarEventTests`
