Requests an asynchronous CSV export of a completed verification bulk. One file is generated per entity. The company is always taken from the API key, never from the request body.

Requests are idempotent: the same bulk_id with the same entities returns 202 with the same export_id instead of generating a duplicate. A failed or expired export can be requested again.

When the files are ready, the export.completed webhook event is sent (no download links in the event). Webhooks created before this feature launched must subscribe to the event via PATCH /webhooks/{webhook_id}.
