Marko Djordjevic f94d16c6ab fix: implement real health checks in ML service /health endpoint 
- Execute SELECT 1 against PostgreSQL via SQLAlchemy session to verify DB connectivity
- HTTP GET to ${MLFLOW_TRACKING_URI}/health (default: http://localhost:5000/health) to verify MLflow
- Return HTTP 503 if any component is unhealthy, HTTP 200 only when both are healthy
- Values: "healthy" / "unhealthy" for database and mlflow fields
- Add `import requests as http_requests` and `sa_text` imports

Closes task 5.6 in openspec/changes/code-review-fix/tasks.md
