fix: patch OIDC consent flow regression and add CI build step

The OIDC app 1.16.2 broke the consent flow by only falling back to
session params when client_id is missing. After consent, the redirect
includes client_id and scope but loses state, response_type, and
redirect_uri — causing a 500. The submodule fix restores per-param
session fallback when ANY critical param is missing.

Also adds a CI build step for the OIDC app (composer + npm) so the
JS assets (oidc-consent.js, oidc-redirect.js) are available in OAuth
test profiles.
