Tailnet name (atlas-snares.ts.net) is now sourced from
config.private-flake.tailnetDomain, defined in private-flake's
shared/tailnet.nix and imported by the hetznix01 and nixnuc modules.
WiFi SSIDs for kiosk-* hosts are now set by private-flake's
shared/kiosk.nix via nixosModules.private.kiosk; the hardcoded network
blocks are removed from the kiosk dots configs.
