Subject: [PATCH] chore: bump base image to bookworm and refresh action
 versions

Bullseye is on its way to LTS-only support and the monthly publish
workflow had been disabled by GitHub for inactivity, leaving the image
stale since 2025-10. Moving to bookworm-slim brings a newer NUT and a
supported base; the build-push-action v5 -> v6 bump keeps the build
toolchain current. Pushing this commit also re-enables the scheduled
workflow.
