Replace per-host host-token.nix imports with a single beszel-token secret
in secrets/common.yaml, wired once in enable-agent.nix. Host files now only
need services.beszel.agent.environment.KEY — no imports block required.
Delete modules/beszel/host-token.nix (no longer referenced anywhere).
Action needed: run `sops secrets/common.yaml` and add `beszel-token: <value>`
from the beszel hub UI before deploying.

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

Adds proxmox-ha-server-1 and proxmox-ha-server-2 as real mkTarget entries
alongside the existing proxmox-server, backed by a new ha-server build type.
New modules
modules/ha/cluster-config.nix — DRBD resource + corosync nodelist sourced
from vars (haServer1Host/Ip, haServer2Host/Ip); resource-only fencing for
production STONITH; HA port firewall rules for DRBD, iSCSI, Corosync, pcsd
modules/build-types/ha-server.nix — imports pacemaker-stack + iscsi-target
+ cluster-config + beszel; NFS exports from vars.haStorageRoot (XFS-over-DRBD
mount); nfs-server.service.wantedBy force-cleared so Pacemaker controls
start/stop on the Active node only
New hosts
hosts/ha-server-{1,2}/host.nix — static IP from vars, unique hostId; sops
secrets (beszel, corosync authkey) are TODOs pending sync-host-keys.sh
variables.nix
haServer1/2Host, haServer1/2Ip, haServerVip, haStorageRoot, haIscsiIqn
ports.haServerDrbd/Iscsi/Corosync{1,2,Crypto}/PacemakerRemoted/Pcsd
scripts/ha/ (migrated + updated from test-lab/ha/)
cluster-init.sh — generates corosync authkey, initialises DRBD/XFS/iSCSI,
creates NFS dataset dirs, configures Pacemaker with DRBD + XFS + iSCSI
+ nfs-server + VIP; STONITH disabled initially (enable separately)
cluster-enable-stonith.sh — enables fence_pve_ssh STONITH after key deploy
fence-pve-ssh.py — Proxmox SSH fence agent (node names updated to ha-server-1/2)
acceptance-tests.sh — T1–T7 production acceptance tests
test-lab/ha/ removed — all Nix config moved to modules/ha/ and
modules/build-types/; scripts moved to scripts/ha/
