CHW-4117 SSONotConfigured

SSO is not configured for this organization

Default message: SSO is not configured for this organization
HTTP status: 404 (client)

Problem. The requested SSO operation targets an org with no provider row. Cause. /sso/init, /sso DELETE, /sso/test, or a group-mappings mutation was called before the SSO config was created. Fix. Create the SSO provider with PUT /api/orgs/{org}/sso before calling this endpoint. HTTP 404 (or 400 for /sso/init when the provider exists but is disabled).
