Introduced the NtlmHelper static class in the FakeNTLMServer.Common namespace. This class provides a ValidateCredentials method that uses P/Invoke to call the Windows LogonUser API, allowing validation of NTLM credentials and returning a SafeAccessTokenHandle on success. Constants for logon type and provider are included, and token validity is checked.
