fix: resolve sign-in redirect race condition in Login.tsx

Replace React Router navigate() with window.location.href = '/' after
successful sign-in. Better-Auth's useSession() hasn't updated its
internal cache when navigate() fires, causing ProtectedRoute to see a
null session and redirect back to /login. A full page reload
reinitializes useSession() with fresh cookie-backed session state.

Also remove the VITE_MOCK_AUTH fallback block that used
setAuthenticated() since the mock auth flow now goes through the same
window.location.href path.
