* Added DriverName method to BunAdapter, GormAdapter, and PgSQLAdapter for consistent driver name handling.
* Updated transaction adapters to include driver name.
* Enhanced mock database implementations for testing with DriverName method.
* Adjusted getTableName functions to accommodate driver-specific naming conventions.
