Refactor cassette-futurism rice from KDE Plasma to XFCE

- Replace KDE Plasma 6 with XFCE desktop environment
- Remove plasma.nix (KDE config), add xfce.nix (XFCE config via xfconf)
- Add picom.nix compositor with CRT green glow effects (#00FF00 shadows)
- Configure XFCE with hidden menubars, dark theme, and retro aesthetics
- Replace KDE packages with XFCE equivalents (konsole→xfce4-terminal, kate→mousepad, gwenview→ristretto, spectacle→xfce4-screenshooter)
- Keep ly display manager, preserve all Stylix theming (cassette colors, NGE wallpaper, fonts)
- Lower memory usage and faster startup compared to KDE Plasma
