fix(commerce-backend): agregar dummies de build para vars de Google OAuth

npm run build (medusa build) carga medusa-config.ts, que ahora exige
GOOGLE_CLIENT_ID/GOOGLE_CLIENT_SECRET/GOOGLE_CALLBACK_URL via required().
Sin valores dummy en el builder stage, el build fallaba con "Error in
loading config: La variable GOOGLE_CLIENT_ID es obligatoria" -- mismo
patron ya usado para JWT_SECRET/MEILISEARCH_API_KEY.
