fix: resolve VM startup failures, broken Hyprland functionality, and theme integration

- Fix QEMU syntax and root filesystem conflicts in vm-guest.nix.
- Repair numerous broken relative paths and imports across the codebase.
- Set 'summer-night' as the default distro theme with full branding integration.
- Implement declarative system-wide font installation including the 'nomarchy' font.
- Fix Waybar startup by dynamically generating theme-aware CSS.
- Restore Hyprland keybindings (Super+Return, Super+Space) and wallpaper loading.
- Add missing scripts: nomarchy-launch-walker, nomarchy-toggle-waybar, nomarchy-refresh-config.
- Enable UWSM and correctly disable conflicting Hyprland systemd services.
