## Summary
- Add Coolify deployment configuration (docker-compose, healthchecks, network setup)
- Replace deploy-hetzner CI job with Coolify webhook deploy
- Externalize postgres, qdrant, S3 for Coolify environment

## All changes since branch creation
- Coolify docker-compose with Traefik labels and healthchecks
- CI pipeline: deploy-hetzner → deploy-coolify (simple webhook curl)
- SQLAlchemy 2.x text() compatibility fixes
- Alpine-compatible Dockerfile fixes
