Emma Thorpe ebff5aeba6 feat(nixos): replace X1 with ThinkPad T400; add Mac Pro 3,1 desktop
- lyrathorpe-t400 replaces lyrathorpe-x1c: ThinkPad T400 (legacy BIOS -> GRUB,
  Intel microcode + redistributable firmware for iwlwifi, pipewire, sshd).
- lyrathorpe-macpro31: new desktop host (portable = false) importing
  desktop.nix. Mac Pro 3,1 has 64-bit EFI -> systemd-boot; wired NetworkManager
  via desktop.nix; desktop status bar (temperature + net, no battery).

Both ship hand-written placeholder hardware-configuration.nix (root/swap/ESP by
label, GRUB device /dev/sda) to be regenerated with nixos-generate-config and
committed at install time. All five host configs evaluate; nixfmt clean.
