Import models and state_choices to ensure registration happens on Django startup.

The @register_state_model and @register_state_choices decorators run during

module import, so we must import these modules to populate the registries.

This ensures state models are available throughout the application lifecycle.

This is the ONLY place in LSO where FSM transitions should be imported.
