Subject: [PATCH] ci: add workflow to publish atryum image to Docker Hub

Add a GitHub Actions workflow that builds the production atryum image
from Dockerfile.prod and pushes it to Docker Hub under validmind/atryum.

- Builds multi-arch images (linux/amd64, linux/arm64) via QEMU + Buildx
- Derives tags with docker/metadata-action: latest and sha on main,
  semver tags on v* releases, and a custom tag on manual dispatch
- Authenticates with DOCKERHUB_USERNAME / DOCKERHUB_TOKEN secrets
- Uses GitHub Actions cache to speed up rebuilds

The org gha-workflows reusable build/push workflows target AWS ECR only,
so a standalone workflow is used for the Docker Hub destination.
