Follow-up to #63050

When the Celery worker starts, it imports app from celery_executor.py but celery_executor_utils.py was never imported at module level. This means execute_workload (and execute_command for Airflow 2.x) are never registered as Celery tasks when the worker boots, causing:

KeyError: 'execute_command'
KeyError: 'execute_workload'
Received unregistered task of type '...'. The message has been ignored and discarded.

Fix is a single module-level import in celery_executor.py so celery_executor_utils is loaded when the worker imports app at startup, ensuring all tasks are registered immediately.

Also adds a regression test to verify task registration on import.

Fixes#63043

Follow-up to #63050

When the Celery worker starts, it imports app from celery_executor.py but celery_executor_utils.py was never imported at module level. This means execute_workload (and execute_command for Airflow 2.x) are never registered as Celery tasks when the worker boots, causing:

KeyError: 'execute_command'
KeyError: 'execute_workload'
Received unregistered task of type '...'. The message has been ignored and discarded.

Fix is a single module-level import in celery_executor.py so celery_executor_utils is loaded when the worker imports app at startup, ensuring all tasks are registered immediately.

Also adds a regression test to verify task registration on import.

Fixes#63043
