BlazorAuthenticationChallengeHandler
Remarks
This handler is designed specifically for Blazor Server scenarios where authentication challenges need to be initiated from component code. It supports incremental consent (requesting additional scopes) and Conditional Access (handling step-up authentication). Use this in combination with MapLoginAndLogout(IEndpointRouteBuilder) to enable seamless authentication flows in Blazor Server applications.
