fix: remove calamares from CI, add grub-theme and live packages

- Remove calamares from packages.yaml: our fork stripped services-openrc,
  Artix repo provides working calamares (3.4.2-4) with openrc support
- Add antergos-grub-theme to CI: uses real Antergos background + logo
  from grub2-theme-antergos repo merged with Artix UI infrastructure
- Add antergos-live to CI: fork of artix-live with s/artix/antergos branding
- Bump calamares-branding-antergos-next pkgrel 12->13: settings now call
  services-openrc instead of services-systemd, show.qml drops EndeavourOS,
  calamares-next.sh targets /home/antergos not /home/liveuser
