Before making any changes, verify the grid is in a good state: - check_cluster_health: waits for Elasticsearch to reach at least 'yellow' (blocks only on red/unreachable, since yellow is normal), modeled on the wait in so-elasticsearch-roles-load. - check_fleet_server: confirms the Fleet Server status API returns HTTP 200, modeled on the wait_for_so-elastic-fleet state in elasticfleet/enabled.sls. Both run alongside the existing check_pillar_items (manager pillar render) and verify_es_version_compatibility, before soup modifies anything, so a failure exits cleanly with an actionable message and no partial changes. Valid on all manager roles soup runs on (eval/standalone/manager/managerhype/managersearch/ import), which all run Elasticsearch and the Fleet Server.
