Refactor metrics handling and improve logging

- Removed the MetricsManager initialization from `run_helper.py` to avoid duplication, as metrics are now handled in `main.py`.
- Updated logging levels in `server_prometheus.py` and `metrics_middleware.py` to use debug instead of info for less critical messages.
- Added metrics configuration to `BaseDependencyFactory` for better management of metrics settings.
- Deleted the obsolete `metrics_exporter.py` file to streamline the codebase.
- Updated various tests to reflect changes in the metrics handling and ensure proper functionality.
