Subject: [PATCH] feat(streckkod): okand produkt -> fota forpackning -> spara i
 delad katalog

Okand streckkod erbjuder nu 'Fota forpackningen' direkt i streckkodsvyn.
Fotot lases av (naring/allergener/innehall) och produkten UPSERTas i den
DELADE products-katalogen kopplat till GTIN (dataSource=user_scanned,
verificationStatus=unverified, createdByUserId=anvandaren) sa nasta person
som skannar samma kod far den direkt. Produkten laggs INTE till i lagret.

Naringsdeklaration-knappen tas bort som egen ingang - flodet vavs in i
streckkodsskanningen. product_package/nutrition_label -> READ_NUTRITION_LABEL
avslutar som 'completed' med result.product (ingen awaiting_confirmation).

- validation: barcode-falt i createScanInput.context
- worker: ny gren i processScanJob som skriver till products + returnerar tidigt
- mobil: inline contributePhoto (fota -> ladda upp -> polla -> visa info)
- scan: ta bort naringsdeklaration-knappen
- i18n: barcode.contributing.* + uppdaterad unknownBody pa 12 sprak

Verifierat: typecheck (validation/worker/api/mobil), worker 23/23, api 104/104,
och repro mot testdatabas (products-upsert, ingen inventory, idempotent aterskann).
