docker-compose→podman-socket ignores containers.conf pids_limit and always
creates the container with PidsLimit=2048, which KDE Plasma exhausts causing
QThread creation failures and kcrash. Switching to virtualisation.oci-containers
uses podman run directly so --pids-limit=-1 (unlimited) is respected. cgroup
pids.max now shows "max" instead of 2048.

- firewall.nix: allow DNS (UDP/TCP 53) from all podman bridge networks
(10.89.0.0/16); NixOS only auto-adds a rule for podman0 but docker-compose
arion stacks land on podman1/2/3 where container DNS was silently blocked
- vnc-desktop/start.sh: rm stale /tmp/.X1-lock on container start so
container restarts don't leave Xvnc unable to bind display :1
- linux.nix: TasksMax=infinity on arion-vnc-desktop so the systemd cgroup
doesn't cap KDE Plasma's thread count below the container pids limit
- arion-riverside/arion-compose.nix: add ADMIN_PASS env var required by
the riverside entrypoint

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.

- Break systemd ordering deadlock: nginx.after mkForce removes
DNS-challenge ACME services (philippeterson, webdav) from nginx's
After list, which was creating a cycle through nginx-config-reload
back to HTTP-webroot ACME services that need nginx Before them.
- Fix arion services not finding podman socket: arion NixOS module
sets backend=podman-socket but doesn't inject DOCKER_HOST; add
explicit DOCKER_HOST=unix:///run/podman/podman.sock for all three
arion projects.
- Fix gitea-runner startup race: add After/Wants on arion-forgejo so
the runner doesn't try to register before Forgejo is up.
- Fix riverside image reference: pinned digest was stale after a
re-push; switch to :latest.

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.

The directory was created by the old DynamicUser (uid 63182). Add a
tmpfiles rule to guarantee correct ownership after any rebuild.

Create a persistent gitea-runner system user in the docker group instead
of relying on DynamicUser — supplementary groups were silently ignored
with DynamicUser=true, leaving the runner unable to reach the socket.

Jobs now execute directly on the runner host rather than inside a docker
container, giving them access to Node.js, Docker, and other host tools
without needing a custom image.

- Map container port 80 (not 8080) to host 3011
- Mount postgres data at /var/lib/postgresql (postgres 18 changed path)
- Set TRUSTED_HOST env var so Drupal accepts the hostname
- Enable ACME/HTTPS for riverside.coldairnetworks.com with HTTP→HTTPS redirect

riverside needs a postgres sidecar which oci-containers can't express.
Also adds docker to arion PATH (fixes forgejo-arion) and creates
/var/riverside/{files,postgres} state directories.

Systemd services don't source /etc/set-environment, so NIX_PATH was unset
when arion tried to evaluate arion-pkgs.nix via import <nixpkgs>.

Add riverside OCI container (forge.quinefoundation.com/ironmagma/riverside)
on port 3011 with nginx vhost. Fix forgejo-arion service failure by ensuring
nix-instantiate is in PATH when arion evaluates the compose config.
