New "Excluded Entra groups" card on the Security tab. Members of these
groups (nested memberships count) can never sign in with Microsoft, even
if they are in an allowed group.

A hit in the ID token's groups claim refuses immediately. Otherwise the
plugin always asks Microsoft Graph (checkMemberGroups), because a groups
claim can be filtered in the app registration and cannot prove
non-membership. Graph errors refuse the sign-in (fail closed).
