Jede Display-Seite bringt jetzt ihr eigenes Erscheinungsbild mit – der
Empfang sieht anders aus als der Tagungsraum nebenan:

- eigenes Logo (leer = Logo aus den Einstellungen)
- formatfüllendes Hintergrundbild mit einstellbarer Abdunklung (0–90 %),
  damit die Karte auf hellen Fotos lesbar bleibt
- eigene Akzentfarbe für den Knopf (leer = Farbe aus dem Design-Tab)
- Karte wahlweise hell oder dunkel; auf Fotos wirkt dunkel meist ruhiger

Logo und Hintergrund lassen sich hochladen oder als URL hinterlegen; beim
Löschen einer Display-Seite verschwinden die hochgeladenen Dateien mit.

Nebenbei aufgeräumt: das Bildfeld (Vorschau + Upload + URL + Entfernen)
lag als Funktion in admin/settings.php und wird jetzt von beiden Seiten
genutzt – Ui::imageField() für die Darstellung, Upload::resolveField()
für die Auswertung.

Sicherheit: die Akzentfarbe landet in einem style-Attribut, deshalb wird
sie sowohl beim Speichern als auch beim Ausgeben auf eine echte Hex-Farbe
geprüft; ein Test hält das fest.

Migration 0006, database.sql nachgezogen, 4 neue Tests (42 gesamt),
Screenshots ergänzt, Version 2.8.0.
