fix(database): update affected rows tracking in Database class

- Enhanced the logic for tracking affected rows in the Database class to accurately reflect the number of rows modified by INSERT, UPDATE, and DELETE operations using the getRowCount() method.
- Added a new unit test suite for the affected_rows method, ensuring comprehensive coverage for various scenarios including tracking of affected rows and validation of the last_affected_rows property.

This update improves the reliability of the Database class's affected rows reporting, facilitating better data handling and debugging.
