Show the next alarm 24 hours ahead, not 8

An alarm set for the next morning left the dynamic zone before it was visible:
at 22:00 an alarm at 06:00 is eight hours away, so the part only appeared while
the phone was unlikely to be looked at. The window is now 24 hours, and the
setting summary says so (also in Danish; the other translations still say 8 and
will follow upstream).

Verified on the Titan 2 that Chrono (com.vicolo.chrono) registers its alarms the
way this part reads them: dumpsys alarm lists them as "Alarm clock" entries with
a showIntent pointing at Chrono, and AlarmManager.nextAlarmClock returns the
earliest one, so ACTION_NEXT_ALARM_CLOCK_CHANGED keeps the part up to date.
Tapping it opens Chrono as well - SHOW_ALARMS, SET_ALARM and SHOW_TIMERS all
resolve to com.vicolo.chrono/.MainActivity.
