refactor: centralize error handling utilities across route modules

- Introduced a new common utility module for error handling, providing consistent methods for retrieving error messages and logging errors.
- Updated individual route modules to utilize the shared error handling functions, reducing code duplication and improving maintainability.
- Ensured all routes now log errors in a standardized format, enhancing debugging and monitoring capabilities.
