Add login button to 'No Session' toast notifications

Add 'Iniciar Sesión' button to toasts when session is not active.
Clicking the button reloads the page, triggering Authentik redirect
to login flow.

Also increased toast timeout from 5s to 10s to give users more time
to see and click the login button.
