✨(backend) add S3 objects

Inspired by Impress and @sampaccoud's work.

We use Indie Hoster’s Kubernetes objects in staging and production.
In the "dev" environment, we install the `bitnami/minio` chart to mimic
Indie Hoster’s MinIO setup.

To access the MinIO admin interface in dev, use port forwarding;
the interface runs on port 9001.
