feat(commerce-backend): habilitar login con Google via Medusa auth module

Agrega el modulo @medusajs/medusa/auth con providers emailpass (explicito,
para no perder el default al customizar el modulo) y google, leyendo
GOOGLE_CLIENT_ID/GOOGLE_CLIENT_SECRET/GOOGLE_CALLBACK_URL desde
commerce-secrets con required().
