Configurable Default Authentication Method for Login Screen

NetBrain currently defaults the login screen to the local NetBrain authentication method, requiring users to manually switch to SSO each time they log in, even in environments where every user authenticates exclusively through SSO. This enhancement would allow administrators to configure SSO as the default authentication method presented on the login screen. Customers operating in SSO-only environments would benefit from a streamlined login experience, reducing unnecessary manual steps for every user session.
