Complete the rename so all identifiers match networking.hostName:
- flake.nix: attribute names and buildType strings
(linode/proxmox/lxc-tailscale-subnet-router → *-tailscale-router)
- modules/build-types/tailscale-subnet-router.nix → tailscale-router.nix
- .sops.yaml: anchor and alias names (age keys unchanged, no re-encrypt needed)
- host-keys/: local gitignored key files renamed (not committed)
