Subject: [PATCH] fix: usar region_id en vez de currency_code para precios de
 Medusa
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

El validador de /store/products (StoreGetProductsParams, .strict()) solo
acepta region_id/country_code/province/cart_id para resolver contexto de
precio -- currency_code como campo plano no existe y rompía con 400
"Unrecognized fields: 'currency_code'" en cada carga de /catalog.

country_code tampoco alcanza: probado en vivo, devuelve "Missing required
pricing context to calculate prices - region_id". Se necesita region_id
explícito.

Se agrega MEDUSA_REGION_ID (env var) apuntando a la región "Colombia"
(COP) creada vía Admin API, ya que no existía ninguna región configurada
en el backend.
