- Introduced a new configuration file `.cursorrules` to define coding standards, error handling, testing requirements, and project-specific guidelines. - Refactored `config.py` to implement a `Settings` dataclass for better management of environment variables, improving testability and maintainability. - Updated the import duty schedule handler to utilize session management with `session_scope`, ensuring proper database session handling. - Enhanced the import service to streamline the duty schedule import process, improving code organization and readability. - Added new service layer functions to encapsulate business logic related to group duty pinning and duty schedule imports. - Updated README documentation to reflect the new configuration structure and improved import functionality.
