Bundle multiple day-wide events into a single notification

When all-day event alert times trigger, multiple events (overdue tasks,
birthdays, holidays) previously fired individual notifications — one
sound and one popup each. With 8-10 events this was overwhelming.

Now multiple day-wide events are bundled into a single notification
with all messages joined by newlines. Single events still notify
normally without bundling.
