The old DomainFavicon component had a multi-step fallback chain (HTML scraping,
direct URL guessing, then the configured provider) which meant the configurable
setting was almost never reached. The new ExternalFavicon component uses the
configured favicon URL template directly via RFC 6570 URI templates.
- Rename config field faviconProvider -> faviconUrl
- Add faviconUrl() utility with uri-templates for RFC 6570 support
- Remove local Favicon component from ProfileRightSidebar
- Update all consumers to use ExternalFavicon
