"""Smoke test for ``application.worker.attachment_worker``.

The happy path parses an uploaded file and inserts a row into
``attachments``. We mock the parser boundary (``StorageCreator.get_storage``
returns a storage whose ``process_file`` produces a pre-built Document)
but let the PG insert run against the ephemeral ``pg_conn`` so we can
assert one concrete row is visible after the task returns.
