feat(settings): add educational links about relays in reader view

- Add message with links to learn about relays (nostr.how and substack article)
- Links open in Boris's reader view via /r/ route instead of external tabs
- Close settings panel when links are clicked to show the content
- Use react-router navigation for seamless in-app experience
