fix(repo): Handle framework query param in Next.js keyless test

Update the Next.js keyless integration test to verify that claim URLs
include the framework=nextjs query parameter.

This aligns with backend changes that add framework query params to
claim URLs for dashboard analytics and proper routing.

Changes:
- Check for 'framework=nextjs' in sign_in_force_redirect_url
- Check for 'framework=nextjs' in sign_up_force_redirect_url (both regular and prepare-account cases)
- Use .includes() instead of .startsWith() for more flexible URL validation
- Properly handle URL-encoded framework parameter in prepare-account flow

Test coverage:
✅ Sign-in redirect URL contains framework=nextjs
✅ Sign-up redirect URL contains framework=nextjs (regular case)
✅ Sign-up redirect URL contains framework=nextjs (prepare-account case)
✅ All other claim URL parameters (token, dashboard URL) still validated
