Refactor logging implementation and update imports

- Moved the logger instance to a new `logger.ts` file for better organization and reusability.
- Updated import paths in `index.ts`, `index.test.ts`, and `schedules.ts` to reference the new logger module.
- Ensured that the logger is consistently used across the application, improving maintainability and clarity.

These changes streamline the logging setup and enhance code structure.
