feat(new-device-verification-screen): (Auth) [PM-17489] Back Button on New Device Verification Screen (#16599)

On Web and Desktop, show back button on `NewDeviceVerificationComponent` (route `/device-verification`). Do not show it on Extension, because Extension already has a back button in the header.
