feat(auth): [PM-15945] Add logout option to TDE approval page (#12445)

This PR adds a logout option to the TDE approval screen. A TDE user on this page cannot use the "Back" button or click the Bitwarden logo to navigate back to `/` because the user is currently authenticated, which means that navigating to the `/` route would activate the `redirectGuard` and simply route the user back to `/login-initiated`. So we must log the user out first before routing.
