PM-Vorschau: echtes Portal-Design, Direkt-Button und Portal-Switch

Der Vorschau-Link (/pm-vorschau/{token}) renderte eine schlichte
Standalone-Seite, die dem spaeteren Erscheinungsbild nicht entsprach.
Jetzt rendert er die echte Detailseite (web.release-detail) im Theme
des Zielportals:

- Controller wendet Domain-/Theme-Konfig des Zielportals an (Sprache
  der PM, Links zeigen auf die Portal-Domain), kein Hit-Zaehler
- Gelbes Vorschau-Banner mit Status und Link-Gueltigkeit; noindex per
  Meta-Tag + X-Robots-Tag-Header, Canonical entfaellt bei noindex
  (neue robots-Section im Web-Layout)
- Teilen-Buttons teilen den Vorschau-Link selbst (oeffentliche URL
  existiert vor Veroeffentlichung noch nicht)
- PMs fuer beide Portale: ?portal=... waehlt die Ansicht, Umschalter
  im Banner; im Kundenpanel je Portal ein Vorschau-Button, sonst ein
  einzelner "Vorschau oeffnen"-Button (Link-Feld jetzt kopierbar)
- Alte press-release-preview-View entfernt
