Show why personal OIDC logins are refused

Personal Google and Microsoft accounts were rejected with a raw
JSON unauthorized response after the OIDC callback. Redirect to a
dedicated auth page that explains the enterprise-account
requirement, and check enterprise eligibility before xms_edov so
Microsoft consumer accounts get the same clear error.
