Simplify conference flow: demo account stays logged in

- Demo users always redirect to welcome screen from /
- Remove auto-login complexity from welcome.html
- Add /app route for authenticated access to main form
- Add Welcome button to form header for easy navigation
- Conference setup: Ishita logs in once, visitors use welcome screen
- Eliminates authentication friction during conference demonstrations
