Delete asset

Permanently delete an asset.

Returns 409 when the asset is still used by live course content — as a lesson's content, a lesson content item, a lesson attachment, or a course promo video. Otherwise the asset is deleted and 204 is returned.

This is a hard delete. Unlike web packages, assets are not soft-deleted: the record is removed and its JW Platform video and stored file are torn down with it. There is no recovery.

By-id rather than a batch envelope: the conflict outcome has no natural home in a per-row batch result, and batch-responses.md warns against letting a ConflictError fall through the document-level path mid-batch. Matches DELETE /v2/web-packages/{id}.
