Switch to host networking so LibreChat can reach Keycloak on localhost.
Patch openidStrategy.js to allow HTTP OIDC issuers for local dev
(openid-client v6 enforces HTTPS by default). Add support for
OPENID_AUTH_EXTRA_PARAMS env var and set prompt=none for automatic
SSO login when a Keycloak session exists.
