TRUNK-6646: Env-var key normalization drops create_database_* / create_user_* credentials in scripted setup

[jwnasambu]

Description of what I changed

I expanded NON_NORMALIZED_KEYS: By adding the following keys to the allow list to prevent incorrect normalization (preserving underscores):
* CONNECTION_DRIVER_CLASS
* CREATE_DATABASE_USERNAME
* CREATE_DATABASE_PASSWORD
* CREATE_USER_USERNAME
* CREATE_USER_PASSWORD
Also I updated the initializeWizardFromResolvedPropertiesIfPresent method to resolve the database driver from both connection.driver_class (dot notation) and connection_driver_class (underscore notation). This ensures compatibility regardless of whether the value comes from a runtime properties file or a normalized environment variable.
