feat(ecommerce): version real del footer via APP_VERSION

El footer mostraba "v4.1" fijo -- inutil para distinguir a simple
vista si Staging y Produccion estan en la misma version. Ahora lee
process.env.APP_VERSION, que el propio CD (.gitea/workflows/build.yaml)
bumpea junto con el tag de la imagen en cada auto-deploy a Staging.
