Adapt devcontainer.json for systemd-based devcontainer image (#131)

* Adapt devcontainer.json for systemd-based devcontainer image

Update devcontainer.json settings to work with the new systemd-based
devcontainer image (v4).

- Update name to mention apps instead of add-ons
- Use same order of elements as in devcontainer template
- Bump image tag to 4-supervisor to get the systemd-enabled image
- Set overrideCommand to false so the image's CMD (/sbin/init) runs
  as PID 1 instead of being replaced by VS Code's default sleep command
- Set remoteUser to vscode to preserve the non-root shell experience
  (required when overrideCommand is false, since VS Code no longer
  injects its own user-switching wrapper)
- Add /var/lib/containerd volume mount because modern Docker uses the
  containerd snapshotter, which stores layer data outside
  /var/lib/docker
- Add tmpfs on /tmp to match typical systemd expectations and avoid
  leftover state across container restarts

* Use apps command instead of deprecated addons command in tasks.json

* Add install app command to tasks.json

* Use ha apps command for log captureing
