Replace TTY/getty login with a graphical Wayland greeter on every host
with features.swayDesktop enabled (MBP, T400, Mac Pro; not the WSL box).
greetd launches ReGreet inside the cage kiosk compositor; the Sway
session is listed automatically via services.displayManager.sessionPackages.
Override regreet's mkDefault greetd command to export
XKB_DEFAULT_LAYOUT=dvorak so the greeter password field matches the
console (workstation.nix) and Sway session (home/sway.nix) layout.
