- Galerien sind nun eine Entität - es kann mehrere geben

- Neues Sparkbooth-Upload-Feature: Endpoint /api/sparkbooth/upload (Token-basiert pro Galerie), Controller Api/SparkboothUploadController, Migration 2026_01_21_000001_add_upload_fields_to_galleries_table.php mit Upload-Flags/Token/Expiry;
    Galerie-Modell und Factory/Seeder entsprechend erweitert.
  - Filament: Neue Setup-Seite SparkboothSetup (mit View) zur schnellen Galerie- und Token-Erstellung inkl. QR/Endpoint/Snippet;
    Galerie-Link-Views nutzen jetzt simple-qrcode (Composer-Dependency hinzugefügt) und bieten PNG-Download.
  - Galerie-Tabelle: Slug/Pfad-Spalten entfernt, Action „Link-Details“ mit Modal; Created-at-Spalte hinzugefügt.
  - Zugriffshärtung: Galerie-IDs in API (ImageController, Download/Print) geprüft; GalleryAccess/Middleware + Gallery-Modell/Slug-UUID
    eingeführt; GalleryAccess-Inertia-Seite.
  - UI/UX: LoadingSpinner/StyledImageDisplay verbessert, Delete-Confirm, Übersetzungen ergänzt.
