The previous rule only caught date-only strings. A multi-day event sent with
full timestamps and no allDay flag still arrived as a timed event, so a holiday
running from the 16th to the 21st rendered as a one-hour slot at midnight.
Now an event that starts and ends on a day boundary and covers at least one
whole day is all-day regardless. That is a statement about what the data means,
not about how any one client formats it, which is why it lives in the parser
and not in a view.
