feat(config): Add configurable workers and host settings

- Add "workers" configuration option to DEFAULT_CONFIG with default value of 1
- Add "host" configuration option to DEFAULT_CONFIG with default value of "::"
- Update uvicorn.run() to use settings.host and settings.workers instead of hardcoded values
- Reorganize imports in main.py for better readability and consistency
- Add blank line after time import in core/utils.py for PEP 8 compliance
- Allow dynamic configuration of server workers and binding host address
