feat(scanner): ean-barcode mit der handykamera scannen

Browse Source 
Knopf im Katalog neben "Set anlegen": Strichcode ins Bild halten, und
entweder oeffnet sich das passende Set oder das Formular "Neues Set"
mit ausgefuellter EAN. Dekodiert wird im Browser mit zxing, das nur
beim Oeffnen des Scanners nachgeladen wird - nichts verlaesst das
Geraet, und die Katalogseite bleibt leicht fuer alle, die nie scannen.

Jeder gelesene Code wird gegen seine Pruefziffer geprueft, bevor er
verwendet wird. Ohne das wuerde eine falsch erkannte Ziffer stillschweigend
ein zweites Katalog-Set fuer ein Set anlegen, das es schon gibt; bei
einem Fehlversuch scannt die Kamera einfach weiter.

Die Kamera braucht wie Passkeys einen sicheren Kontext. Fehlt HTTPS oder
wird der Zugriff abgelehnt, steht das als deutscher Hinweis im Dialog
statt einer stummen schwarzen Flaeche.

8 Unit-Tests mit echten EAN-13-, EAN-8- und UPC-A-Beispielen.
