fix: simplify MiroFlow engine-proxy, remove broken KG registration

- Remove unused crypto import and broken createNode dependency
- Delete registerExecutionInKG function (was fully commented)
- Clean up excessive console.logs
- Streamline POST /api/miroflow/analyze route
- Routes should now register cleanly without initialization errors

This fixes the TypeError that was preventing route registration.
