shopPRO's products/update clears ALL language fields (name, description,
short_description, etc.) for any language not included in the payload.
Sending only {"categories":[...]} wiped them out.
saveProductCategoriesJson() now:
1. Looks up the local orderPRO product via findMappedProductId()
2. Loads per-integration translation (with global fallback)
3. Includes languages.pl in the payload alongside categories
Also adds ProductRepository to MarketplaceController constructor.
