minute: add MinuteLoginUrl output with embedded basic auth credentials

Pasting the URL into a browser address bar prompts a basic-auth challenge,
forcing users to copy-paste the BasicAuthUsername and BasicAuthPassword
outputs separately. The new MinuteLoginUrl output is the same URL with
admin:<generated-password>@ already embedded so it loads in one click.
