Root SSH was failing because only the RSA admin key was authorized but the
local dev box only has an ed25519 key. Fix:
- cluster-config.nix: add ed25519 keys to root (same set as nixos user) so
future deployments work without the temp-key workaround
- deploy.sh/acceptance-tests.sh: SSH as nixos user with sudo instead of root@
- cluster-init.sh: HA_USER/HA_KEY env vars + n2_ssh()/n2_scp() helpers so
inter-node SSH works regardless of whether root-to-root is available
- deploy.sh Phase 6: generate temp keypair, authorize on node2, place on node1
for root to use during cluster-init, clean up afterward

- Add root SSH key + passwordless sudo to ha-server nodes (needed for
deploy script to run cluster-init.sh via SSH as root on node1)
- Fix cluster-init.sh: correct default IPs (228/227/229 per variables.nix),
use \${VAR:-default} for all config so deploy.sh can override via env
- Fix acceptance-tests.sh: same IP corrections, add -i flag to SSH calls,
use \${VAR:-default} pattern
- Fix deploy.sh dry-run bugs: pve_check() always runs SSH for read-only
probes so bridge existence check is accurate; wait_for_ssh skips in
dry-run instead of timing out
- Fix cluster-init invocation: upload script via scp and run via SSH as
root on node1 (was incorrectly trying to run the script locally)
- Fix acceptance-tests invocation: pass IP env vars from deploy.sh

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/
