KDE mínimo: instala Plasma curado en setup.sh, no el grupo plasma

Mismo enfoque que GNOME mínimo: se quita el profile_config (archinstall solo
base) y kde/setup.sh instala un Plasma curado (plasma-desktop, sddm, plasma-pa,
plasma-nm, powerdevil, kscreen, systemsettings, konsole, dolphin, kate, ark,
spectacle, kcalc, gwenview, okular) + drivers open-source, y habilita sddm.
