feat(bff): POST /self-service/registrations/{id}/withdraw, owner-scoped (refs #12)

The domain withdraw command carries the caller's bsn and owner-scopes the aggregate; unknown or

not-owned is 404 (indistinguishable). The BFF forwards the DigiD token's bsn and relays 204/404.

Regenerate the OpenAPI spec + Angular client for the new endpoint.
