feat(dataplane): add service dep graph and leveled execution

- dependsOn on services; deployment plan is a topological sort into
  levels that run concurrently
- services without dependsOn depend on their list predecessor, so
  existing deployments keep serial order
- unresolvable dependsOn refs are skipped with a log message
- build per-service AnsibleEE spec only at job start; split Deploy
  into startLevel/isLevelReady
