Autor-Seiten: /authors/<slug>/ (rundes Bild, Name, Bio, zentriert) + Byline-Link

- layouts/authors/single.html rendert die Autor-Seite zentriert
- Byline in single.html + index.html verlinkt den Autornamen zu /authors/<urlize name>/
  (nur wenn die Seite existiert)
- CMS-Profil-Speichern schreibt content/authors/<slug>.md (aus Name/Bio/Avatar)
  + data/authors.json und baut public neu → Seite & Links sofort live
- Autor-Seiten aus dem Inhalts-Editor ausgeblendet (über „Profil" verwaltet)
- custom.css: .author-page / -photo / -name / -bio + Byline-Link-Stil
