fix: auto-bootstrap Outline team on fresh install

On a fresh DB Outline shows a blank login page because there is no team
and emailSigninEnabled = false. Add idempotent Ansible tasks that:
1. Create the 'Visual' team if none exists
2. Set guestSignin=true so email magic-link login works
Triggered by: server rebuild lost Outline DB (no backup existed).
