fix(GRO-689): only validate authorizationUrl hostname, add OIDC_INTERNAL_BASE in dev

- Move hostname validation to run AFTER OIDC_INTERNAL_BASE replacement
  (was checking raw discovery URLs before replacement caused false positives)
- Only validate authorizationUrl hostname against issuer; token/userinfo
  are server-to-server and may legitimately use internal hostnames
- Infra: add OIDC_INTERNAL_BASE env var to dev overlay (was missing, matches UAT)
