refactor(scheduler): use the recipe's default stateful schedule

Consolidate onto the symfony/scheduler recipe's App\Schedule (stateful +
processOnlyLastMissedRun, so missed runs after downtime still execute)
instead of a separate provider. Add the every-1-minute
ExpireAppointmentsMessage there, point scheduler_default at
schedule://default, and drop the redundant ExpireAppointmentsSchedule.
debug:scheduler shows the trigger registered.
