"""Confirms every FC-2a task module imports cleanly and registers with Celery.

Celery's `include=[...]` parameter on the Celery() constructor is lazy — it
only imports those modules when a worker boots. To assert task registration
in a plain pytest run we explicitly import the task modules ourselves.
