highstate_interval_hours describes the per-minion highstate schedule, not the
active-push pipeline, so relocate it from salt.auto_apply to a new salt.schedule
settings subtree. Repoint so-salt-minion-check at the new pillar path (it had
been left on the stale global:push path) so its restart grace period tracks the
schedule again.
- Add salt.schedule.highstate_interval_hours to defaults.yaml/soc_salt.yaml and a
side-effect-free salt/salt/schedule.map.jinja (SCHEDULEMERGED), matching the
*MERGED map convention. Consumers read SCHEDULEMERGED.highstate_interval_hours.
- Split salt/schedule.sls into salt/salt/highstate_schedule.sls (every minion) and
salt/salt/push_drain_schedule.sls (managers); update top.sls to apply the
highstate schedule via '*' and the drainer schedule via the configured-manager
block. Remove the now-empty schedule.sls aggregator.
- pillar_push_map.yaml and so-push-drainer: comment/doc updates only.
