feat: favicons in bottom nav + 3-dot menu on recent rows

- Pinned web favorites in the bottom navigation now show the captured favicon
  instead of the generic globe (falling back to the globe until one is
  captured). Resolved via BrowserIconRegistry, same as the launcher cards.
- Each Recent row in the browser home gains a 3-dot overflow menu to add the
  URL to favorites (or remove it if already favorited) and to remove it from
  history. Replaces the prior long-press-to-remove with a discoverable menu;
  the row icon shows a star once the site is favorited.
