fix: replace unhandled throw with logger.e in FAQ screen launchUrl

_launchURL() in faq_screen.dart threw a raw string when canLaunchUrl
returned false. This throw was never caught at the call site
(onTap: () => _launchURL(faq.linkUrl!)), so it propagated up and
crashed the app instead of failing gracefully.

Replaced the throw with logger.e(), consistent with how launchUrl
failures are already handled in about_us_screen.dart.

Fixes #3384
