Mike Reeves a0cf0489d6 reduce highstate frequency with active push for rules and pillars
- schedule highstate every 2 hours (was 15 minutes); interval lives in
  global:push:highstate_interval_hours so the SOC admin UI can tune it and
  so-salt-minion-check derives its threshold as (interval + 1) * 3600
- add inotify beacon on the manager + master reactor + orch.push_batch that
  writes per-app intent files, with a so-push-drainer schedule on the manager
  that debounces, dedupes, and dispatches a single orchestration
- pillar_push_map.yaml allowlists the apps whose pillar changes trigger an
  immediate targeted state.apply (targets verified against salt/top.sls);
  edits under pillar/minions/ trigger a state.highstate on that one minion
- host-batch every push orchestration (batch: 25%, batch_wait: 15) so rule
  changes don't thundering-herd large fleets
- new global:push:enabled kill-switch tears down the beacon, reactor config,
  and drainer schedule on the next highstate for operators who want to keep
  highstate-only behavior
- set restart_policy: unless-stopped on 23 container states so docker
  recovers crashes without waiting for the next highstate; leave registry
  (always), strelka/backend (on-failure), kratos, and hydra alone with
  inline comments explaining why
