feat(katalog): set-katalog mit filtern, detailseite und uploads
Kachelliste mit Suche ueber Setnummer, Name und EAN sowie Filtern nach Hersteller, Thema, Jahr und Besitzstatus. Besitz kommt aus genau einer Stelle: src/lib/ownership.ts definiert "hat er nicht" als Katalogeintrag ohne collection_item mit Status ungleich sold, als korrelierte Subquery, damit mehrere Exemplare die Liste nicht verdoppeln. Detailseite mit Metadaten, Anleitungen (PDF-Upload plus pdf.js-Viewer ohne CDN, oder externer Link), Fotos, Sammlungseintraegen und den Aktionen "Zur Sammlung" und "Auf Wunschliste". Upload-Pipeline prueft Magic Bytes statt des gemeldeten MIME-Typs, erzeugt Dateinamen serverseitig, wandelt Bilder in WebP inklusive Thumbnail und liefert Dateien ueber /api/files aus - Set-Bilder oeffentlich, Fotos und PDFs nur mit Session. Dazu das Seed-Skript mit 3 Herstellern, 6 Themen, 10 Sets und 4 Sammlungseintraegen. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
