fix: use external network for dev compose to avoid label conflicts

The portfolio_dev network was created manually by the pipeline, causing
docker-compose to fail with label mismatch errors. Now:
- Network is marked as external in compose (compose doesn't try to own it)
- Network creation moved before compose up in the pipeline
- Redundant network check later in pipeline removed
