Streams the exported CSV with Content-Disposition: attachment. Returns 422 with code: export_not_ready while done is still false. The endpoint is JWT/API-key protected, so SPA clients must fetch it (with Authorization header) and trigger the browser download via a Blob URL — a top-level navigation cannot carry the JWT.
Required scope: read_exports (for API-key authentication).
