fix(alarm): honor the persisted trigger on reschedule so app updates stop re-arming the wrong day

reschedulePersistedAlarms re-armed every stored alarm through the native
recompute engine (trustDartTrigger defaulted to false). That engine can
diverge from Dart's next-occurrence verdict and arm the alarm for the
wrong day, so it silently never fires. Because this runs on boot, unlock
and ACTION_MY_PACKAGE_REPLACED (which fires on every app install), each
new build re-broke correctly-armed alarms while snooze kept working
(snooze never touches the recompute for its trigger value).

Trust the persisted trigger (Dart's own verdict, saved when the alarm was
last armed) whenever it is still in the future; a genuinely stale past
trigger still falls back to the native recompute inside scheduleSpec.
