WGU prep: Windows VM setup, trackpad/trackpoint tweaks, aliases

- Add WGU Windows VM helper script + virtualization module (KVM/libvirt)
- Fix create-wgu-vn: mkdir before use, CPU topology, detect OS variant
- Add Webex, ZapZap, qalculate-gtk, libqalculate, tigervnc packages
- Add n97-mini VNC alias, switch nr to local flake path
- Tune trackpad (0.44) and TrackPoint (160/120) sensitivity
- Reduce mouse sensitivity to -0.2
- Move zapzap from desktop.nix alphabetically
- Remove OVMFFull from virtualisation (handled by swtpm/OVMF default)
- Bump flake inputs (home-manager, nixos-hardware, nixpkgs, pi-mono)
