fix(mcp v2.4.7): defer coolify-proxy restart so it doesn't kill our own request

The post-deploy step that restarts coolify-proxy was running
synchronously inside the HTTP request handler. coolify-proxy is the
same gateway that's serving the request itself, so the restart
killed our outbound response mid-flight — the agent saw curl exit
16 (HTTP/2 framing error) instead of our nicely-formatted result.

Switch to a fire-and-forget shell:
  nohup sh -c '(sleep 3 && docker restart coolify-proxy) ...' &

The SSH command returns within ~50ms, we finish the HTTP response,
and Traefik re-discovers labels 3s later — same end state as before
but without breaking the calling request.
