Move 50 auth/accounts/permissions/JWT/NKey test files from NATS.Server.Tests into a dedicated NATS.Server.Auth.Tests project. Update namespaces, replace private GetFreePort/ReadUntilAsync helpers with TestUtilities calls, replace Task.Delay with TaskCompletionSource in test doubles, and add InternalsVisibleTo. 690 tests pass.
