Release v1.2.7

Added

• Real-browser end-to-end and accessibility coverage of the lobby's three journeys (join by invitation, invited organization setup, self-service registration), using Playwright and axe. It runs against a real Ante and Chronicle kernel nightly and on pull requests labelled run-integration (#118)

Fixed

• The onboarding wizards showed "Setting up..." instead of their form in a real browser, because the placeholder a query starts with was read as a submitted status. A status now counts only once it arrives for the requested invitation or registration. The host outcome screen and the registration page wait for their real answers the same way (#146)
• Wizard step announcements, tab semantics and moving focus to the new step never applied, because the stepper mounts after the page (#147)
• The onboarding wizards could not be submitted when no legal documents are configured (#148)
• The display preferences dialog now closes with Escape (#149)
