fix: switch live session to Wayland, remove plasma-wayland-session, delete Install Artix shortcut

- live-overlay SDDM config was overriding rootfs with Session=plasmax11.desktop
  (X11). Changed to Session=plasma.desktop (Wayland) so the live env actually
  boots into Wayland as intended.
- Removed plasma-wayland-session from profile.yaml packages — Artix bundles
  Wayland session support into plasma-workspace itself; the separate package
  does not exist in Artix repos.
- Deleted calamares-config-switcher.desktop from live-overlay (was previously
  hidden with NoDisplay=true but user reports it still appeared). Now gone
  entirely.
- Cleaned up leftover debug echo statements from earlier sudo -E
  troubleshooting in buildiso.
