SIENTIAPDE-1646

Refactor MLflow configuration to use environment variable for tracking URL

- Removed the `_build_mlflow_tracking_url` function and replaced its usage with `getenv` to directly retrieve the `MLFLOW_URL` environment variable.
- This change simplifies the configuration process by allowing users to specify the tracking URL directly through an environment variable.
