Adds static IP configuration to every NixOS host in the flake that
has a fixed LAN address, and centralises all network primitives
(IPs, gateway, prefix length, interface names) in variables.nix so
there is one place to update if any of them change.
variables.nix additions:
- lanGateway / lanPrefixLength — LAN gateway and /24 prefix, replacing
every hardcoded 192.168.2.254 / 24 across host files
- lxcLanInterface / vmLanInterface / vmStorageInterface — NIC names for
LXC containers (eth0), Proxmox VMs (ens18), and the HA storage NIC
(ens19), used as attribute keys so changing the name is a one-line edit
- haStoragePrefixLength — /29 for the storage subnet, mirrors haStorageCidr
- Per-host IP variables: nixCacheIp (.224), tailscaleRouterIp (.222),
torRelayIp (.221), serverIp (.226), dockerIp (.225)
host.nix changes:
- tailscale-router, tor-relay, nix-cache, pxe-boot: useDHCP = false,
static address on eth0 (lxcLanInterface), struct-form defaultGateway
(required when using systemd-networkd which LXC containers use)
- server, docker: useDHCP = false, static address on ens18 (vmLanInterface),
struct-form defaultGateway (works for both scripted networking and networkd)
- ha-server-1, ha-server-2: replace hardcoded 192.168.2.254 / 24 / 29
with the new variables; no functional change for these hosts
modules/build-types/pxe-boot.nix:
- Domain-controller kickstart template: replace hardcoded 192.168.2.138
and 192.168.2.254 with vars.domainControllerIp / vars.lanGateway /
vars.lanPrefixLength / vars.homeDomain so the template stays correct
if the DC IP or domain is ever changed again

- Add hosts/tor-relay/host.nix import of host-token.nix so the agent
gets its TOKEN from a sops-managed environment file
- Add secrets/tor-relay.yaml (encrypted beszel token for this host)
- Add creation_rules entry for secrets/tor-relay.yaml in .sops.yaml
- Update &lxc-tor-relay age key to the host's actual current key
(old key was from a prior LXC incarnation; new key extracted from
Switch-nix output: age1gl5ujmhd2pe37...)
- Re-encrypt secrets/common.yaml via sops updatekeys to swap in the
new key, so the host can decrypt its password hash on next boot

New tor-relay build type (currently lxc-only) running a plain Tor
middle relay via modules/tor/enable-relay.nix, plus nyx for
interactive monitoring over the relay's control socket.
