TOTP management screens flows

Some feedbacks on our currents 2FA/TOTP management flows:

After registering a TOTP, we stay on the configuration screen, with a success message. It would be better to go back to 2FA manager screen
On 2FA manager screen, when we already have registered a TOTP we see the new TOTP menu. When clicking on it we have an error. Maybe we should directly add the button from the main 2FA manager screen
