Harden smoke test orchestrator and provisioning

 -  Use shared setup-mise action instead of inlining jdx/mise-action
 -  Validate required env vars at startup with clear error messages
 -  Derive harness host from HARNESS_ORIGIN instead of hardcoding
 -  Pass HARNESS_ORIGIN as env var in provision.sh to avoid shell
    expansion in Ruby heredoc
