fix: acceso público a imágenes de storage para WhatsApp y navegador

- Mueve la ruta /storage/{path} fuera del middleware de auth para que
  sea pública; necesario para que los servidores de WhatsApp y el navegador
  puedan cargar imágenes de promociones sin autenticación
- Dockerfile: agrega 'rm -rf public/storage' antes de storage:link para
  evitar que COPY copie la junction de Windows y deje el symlink roto en el contenedor
- Crea .dockerignore: excluye public/storage, .git, .env y artefactos de
  build del contexto de Docker para builds más limpios y seguros
