Improve Scaleway, Yousign and Railway cassettes

The recorded responses carried only the fields the drivers read.
Rewrite them to match the shape the real Scaleway, Yousign and
Railway APIs return (workspaces, status, account_root_user_id,
timezone-qualified timestamps), so the fixtures exercise the drivers
against realistic payloads. The discriminating assertions (email,
role, is_admin, active, MFA) are unchanged and the driver tests
still pass.
