Replace openbox with kde-plasma-desktop + konsole. Build the container
image locally via a oneshot systemd service (build-vnc-image) that runs
before arion-vnc-desktop on each boot. Nix hashes the Dockerfile and
start.sh at eval time so the build is skipped when nothing changed.
No registry push/pull required.

Custom Podman image (forge.quinefoundation.com/ironmagma/vnc-desktop) running
TigerVNC + noVNC + openbox, proxied via nginx with ACME TLS and basic auth.
Also switches all arion projects from docker to podman backend.
