Maps ZB.MOM.WW.Auth, ZB.MOM.WW.Auth.*, ZB.MOM.WW.Audit to the gitea feed
and pins all 4 Auth packages + Audit at 0.1.0. PackageReferences added
during Phase 1/2 adoption.
Central package management requires package-source mapping with >1 feed
(NU1507 as error), so nuget.config scopes ZB.MOM.WW.MxGateway.* to the Gitea
feed and everything else to nuget.org. Credentials are not committed.
