fix: rewrite form filling for new Microsoft Fluent UI signup page

Microsoft redesigned signup.live.com with Fluent UI components:
- Email input: input[name="Email"] (full email, not username+domain)
- Next button: button[data-testid="primaryButton"] (not #nextButton)
- No more liveSwitch toggle
- Added debug screenshots at each step for troubleshooting
