What problems was I solving

The GuestAuthenticationState type was being re-exported from architect/management-ui/app/main/api/session-api.ts, but no code in the repository consumed it through this barrel, creating unnecessary public surface area in the session API layer.

What user-facing changes did I ship

None. This is a non-functional cleanup; no UI strings, behavior, or service contracts changed.

How I implemented it

Updated the single re-export statement in session-api.ts to only export getGuestAuthenticationState, dropping the type GuestAuthenticationState re-export while leaving the upstream type definition untouched in @architect/management-ui-view-model.

Description for the changelog

Removed the unused GuestAuthenticationState type re-export from management-ui/app/main/api/session-api.ts. The getGuestAuthenticationState helper remains exported, and the canonical type is still available from the upstream view-model module.
