RSS/Atom-feed (oppgave 14.8): feed-discovery + betinget RSS-lenke

Feeden i rss.rs var allerede implementert med full RSS 2.0 og Atom 1.0
støtte, inkl. podcast-enclosures. Det som manglet var integrasjon med
publiseringstemplates:

- base.html: <link rel="alternate"> for feed auto-discovery (kun når
  samlingen har rss-trait)
- base.html: RSS-lenke i nav vises kun for samlinger med rss-trait
- publishing.rs: has_rss propageres fra CollectionRow gjennom alle
  render-funksjoner til Tera-kontekst
- CAS-rendering (render_article_to_cas, render_index_to_cas) sjekker
  også rss-trait for korrekt template-kontekst

Verifisert: kompilerer, alle 36 tester passerer, feed.xml returnerer
gyldig RSS/Atom, 404 for ukjente slugs, discovery-link i HTML.
