🪙 fix: Resolve Azure AD Group Overage via OBO Token Exchange for OpenID (#12187)
When Azure AD users belong to 200+ groups, group claims are moved out of
the ID token (overage). The existing resolveGroupsFromOverage() called
Microsoft Graph directly with the app-audience access token, which Graph
rejected (401/403).

Changes:
- Add exchangeTokenForOverage() dedicated OBO exchange with User.Read scope
- Update resolveGroupsFromOverage() to exchange token before Graph call
- Add overage handling to OPENID_ADMIN_ROLE block (was silently failing)
- Share resolved overage groups between required role and admin role checks
- Always resolve via Graph when overage detected (even with partial groups)
- Remove debug-only bypass that forced Graph resolution
- Add tests for OBO exchange, caching, and admin role overage scenarios
