The U7 onboarding view replaced "No accounts yet." with "Welcome to SharedInbox", causing the E2E test to spin for the full timeout budget (pumping slowly in headless CI) before failing. Fix the finder and bump per-attempt timeout from 240s → 360s and CI job ceiling from 20 min → 30 min to give the full account-add → send → verify flow room to complete.
