cms: WYSIWYG-Editor (Toast UI), Profilseite, ziehbare Vorschau, Pill-Optik

- echtes WYSIWYG statt Markdown-Sterne: Formatierung live, speichert Markdown,
  Bild-Upload via Toolbar. Editor nimmt den meisten Platz, Metadaten kompakt oben.
- Vorschau standardmäßig aus (kein toter Raum) + ziehbarer Trenner Editor↔Vorschau.
- Profilseite (Nav Inhalte/Profil): Profilbild-Upload + Kurztext, gespeichert als
  data/authors.json (vom Theme via site.Data.authors nutzbar).
- mehr Pill-Optik (Buttons, Suche, Chips), schwarze Topbar-Navigation.
