refactor(podman): replace deprecated commands with Quadlets

- Replace podman run --restart + podman generate systemd with
  systemd Quadlet .container unit files in /etc/containers/systemd/
- Affects: Home Assistant, Portainer, Portainer Agent
- Remove workaround temp-volume create/remove for Portainer Agent
- Update install check in ct/podman-homeassistant.sh to reference
  the Quadlet file instead of the old generated .service file

podman generate systemd is deprecated since Podman 4.4 in favor of
Quadlets (podman-systemd.unit(5)). Quadlets are natively integrated
into systemd and do not require a running container to generate the
unit file.
