Simplify rice architecture - direct DE and stylix config

- Each rice's system.nix now directly configures desktop environment and stylix
- No complex option system needed - rices just set services directly
- nord-blue: i3 + Nord colors
- cassette-futurism: KDE Plasma 6 + retro cassette colors
- original: i3 + default Nord colors
- Removed rice-desktop.nix complexity
- Display manager (ly) stays in system/services.nix (user-managed)
- To use a rice: mkSystem hostname rice-name in flake.nix
