fix(lasuite): use internal cluster URLs for OIDC backend endpoints

Django backends call the OIDC token, userinfo, and JWKS endpoints
server-side. Pointing these at the public auth.DOMAIN_SUFFIX URL caused
an SSLError in pods because mkcert CA certificates are not trusted inside
containers.

Split the configmap entries:
- OIDC_OP_AUTHORIZATION_ENDPOINT and OIDC_OP_LOGOUT_ENDPOINT remain as
  public HTTPS URLs -- the browser navigates to these.
- OIDC_OP_TOKEN_ENDPOINT, OIDC_OP_USER_ENDPOINT, OIDC_OP_JWKS_ENDPOINT
  now point to http://hydra-public.ory.svc.cluster.local:4444 -- Django
  calls these directly, bypassing the proxy and its TLS certificate.

Affects all La Suite apps (docs, people) that use lasuite-oidc-provider.

+# Backend-to-backend endpoints (token, userinfo, jwks) use the internal cluster
