Display CMS Optimierungen 29-05-2026

- Mediathek: Video-Vorschaubilder statt Icons (FFmpeg-Thumbnails + Backfill-Command), Kategorie "Sonstiges"
- B2in Media-Picker zeigt alle Medientypen, Typ wird automatisch erkannt; Thumbnail-Preview vor allen Medien-URL-Feldern
- B2in Marke/Footer: Footer ein/aus, Logo+Claim frei positionierbar (Ecken) mit Constraints, separate Anzeige-Schalter
- Angebote-Modul dynamisch: kein Slide-Typ mehr, einheitliches Detail-Layout mit ein-/ausblendbaren Bloecken, Logo/Brand pro Slide, Streichpreis-Option
- Player: leere Module stoppen Endlosschleife, dynamische Layout-Anpassung bei verstecktem Footer/Header
- Fix: Script-Ladereihenfolge (Livewire vor Flux), entfernte stale public/flux/flux.js, Modal-Crash beim Aktualisieren behoben
