Function render_upstream_order_json 

pub fn render_upstream_order_json(row: &UpstreamOrderRow) -> Value

One relay upstream_orders row joined to its local order, for acme-proxy upstream order list/show and GET /api/upstream-orders.

Never carries csrDer — UpstreamOrderRow has no such field by design. error and userAgent are untrusted (the upstream CA and the finalize client wrote them); every optional member is omitted when absent.
