GET https://api.craftkit.dev/v1/signatures/:id/download
Streams the archived signed PDF. The signed document is a sensitive legal artifact, so it is served only through the authenticated API (streamed from storage) — it is never reachable from a public bucket URL or a provider-hosted link. Returns 409 until the document has been archived (until signedDownloadUrl is non-null on the request).
