Replaces the Authentik-preset provider with an inline generic OIDC config
(id: "oidc"). The verifier path was already protocol-generic; the only
Authentik-named piece was the next-auth provider preset, which mapped to
the same OIDC fields anyway. Any compliant IdP — Authentik, EntraID,
Keycloak, Okta, Auth0, Zitadel, etc. — now works with just the existing
OIDC_* env vars.
Breaking change for existing deployments: the Auth.js callback path
changes from /api/auth/callback/authentik → /api/auth/callback/oidc.
Update the Web-UI client's redirect URI in your IdP before redeploying.
README rewritten to frame Authentik as the worked example, with a
concept-mapping table for EntraID and Keycloak, and audience-claim notes
for non-Authentik IdPs in the troubleshooting section.
