Fase 2 fix: /store/search acepta region_id para calculated_price

Mismo error encontrado en el gate de verificacion, ahora en la ruta
propia en vez del job de sync: "Method calculatePrices requires
currency_code in the pricing context" -- query.graph necesita
region_id/currency_code en el contexto para resolver
variants.calculated_price. El storefront ya manda region_id contra
/store/products (medusa.ts, regionId()); esta ruta ahora acepta el
mismo query param y arma el contexto de pricing con QueryContext(),
igual que la ruta oficial /store/meilisearch/products del plugin.
