fix: update branding package with correct DE list, initcpio, and launcher fixes

calamares-branding-antergos-next (pkgrel 19):
- calamares-next.sh: fix SetConfig() symlink clobber — rm symlink
  before cp so config is written as standalone file
- show.qml: remove squished logo slider, clean background overlay
  layout, remove Budgie references
- settings_offline.conf: dracut/dracutlukscfg -> initcpiocfg/initcpio/
  luksopenswaphookcfg; services-openrc -> services-artix;
  removeuser -> postcfg
- settings_online.conf: same initcpio/service fixes; netinstall ->
  packagechooser + unpackfs; remove removeuser
- packagechooser.conf: full DE selector with valid Artix groups
  (Plasma, Xfce, Cinnamon, MATE, LXQt, i3, Sway, Hyprland)
  + No Desktop option
