Add unit tests for connectors configuration, logger, workflows, and predictions batch

- Implement tests for MLflow, OPC, and Postgres configuration builders to validate environment variable handling and default values.
- Create tests for the logger to ensure default settings and handler configurations are correct.
- Add comprehensive tests for the FormatAndExportPrediction and PredictionProcess workflows, covering various scenarios including path flags and activity execution.
- Introduce tests for the PredictionsBatch workflow to verify the execution of local activities and child workflows.
- Include a values.yaml file for Kubernetes deployment configuration, specifying image details, service account settings, environment variables, and resource limits.
