fix(dashboard): Bilderrahmen - "1 Stunde" statt "60 Minuten", Bildanzahl in der Einstellungs-Kopfzeile

Zwei Kosmetik-Punkte nach dem Browser-Rundgang vom 21.09.2026:

- Das laengste Wechselintervall (3600 s) hiess "60 Minuten", beim XFrame
  heisst dieselbe Stufe "Jede Stunde". Neuer Schluessel
  `pictureFrame.intervalHours` (ICU-Plural, de + en).
- Unter Einstellungen -> Dashboard zeigte "XFrame #1 - Board" seinen Titel,
  "Bilderrahmen #1" nichts. Die Kopfzeile nennt jetzt "- 1 Bild" bzw.
  "- N Bilder" (Schluessel `imageCountOne`/`imageCountMany`, zwei Schluessel
  statt ICU, weil die Panel-Tests eine einfache Uebersetzungs-Attrappe nutzen).

Web-Tests 603 -> 604, type-check und lint unveraendert gruen.
