feat(send): link every response to the request version that produced it

HTTP snapshots in resolve_send_inputs, the last point in the pipeline that
still holds the stored request — below it the request has been resolved against
its folder and workspace and then rendered, and neither is what a restore
should put back. Every host reaches sending through that function, so the
desktop, the CLI and plugin-triggered sends all get versions without each
knowing about them. gRPC and WebSocket connect do the same at their connection
upserts.

snapshot_request_for_send swallows its own errors: a send is not worth failing
over history that couldn't be written, and an ephemeral request has no id to
version. Either way the response just has no version to offer.
