consolidate all external links through external_link component

Add icon={false} option to external_link for links with their own
visual indicator. Migrate remaining manual target="_blank" links:
email settings adapter links, product show provider edit, card radio
links, social link cards/icons, page renderer tracking and video
fallback. Every external link in the codebase now goes through the
single component — one place to change rel, target, or sr-only text.
