fix: migrate deployment from Hetzner to Coolify (#1)

## 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
- Remove services not needed for SDK deployment (voice, jitsi, synapse)

## All changes since branch creation
- Coolify docker-compose with healthchecks for all services
- CI pipeline: deploy-hetzner → deploy-coolify (simple webhook curl)
- QDRANT_API_KEY support in rag-service
- Alpine-compatible Dockerfile fixes
