feat(qt,gtk): overhaul theming — qt6ct style plugin, dark palette, GTK color-scheme

Qt: replace QT_STYLE_OVERRIDE/QT_STYLE_SHEET env vars with QT_QPA_PLATFORMTHEME=qt6ct +
QT_QUICK_CONTROLS_STYLE=Fusion; add cyberqueer Qt6 style plugin (QProxyStyle wrapping
Fusion with hardcoded dark palette); enable custom_palette in qt6ct.conf so qt6ct applies
the dark QPalette directly for both Qt Widgets and Qt Quick apps.

GTK: fix dark mode not applying — set gtk-application-prefer-dark-theme=1 in GTK3
settings.ini; add gsettings color-scheme=prefer-dark to install script (required by
libadwaita apps which ignore gtk-theme-name); add index.theme so the theme is recognized
by GTK theme discovery.
