Test connection was always 400 because testAuthProviderSchema required clientSecret, but OIDC discovery only needs issuer/internal URLs. Aligned admin test endpoint with setup.ts behavior: - Drop providerId, clientId, clientSecret from schema - Add optional internalBaseUrl; use it for discovery URL when set - Frontend now sends issuerUrl + internalBaseUrl (when populated) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
