Storage VIP (192.168.20.229) is on vmbr2 — an internal-only bridge with no
physical uplink, unreachable from the LAN. Test it via SSH to the active node
(which has VLAN 20 connectivity) instead of directly. LAN VIP (192.168.2.229)
continues to be tested directly from wherever the script runs.
Also adds VIP_LAN variable to config section.

Renumber internal HA bridges so VLAN ID matches IP third octet:
vmbr1 (cluster): 192.168.4.x → 192.168.10.x (VLAN 10, /29)
vmbr2 (storage): 192.168.5.x → 192.168.20.x (VLAN 20, /24)
Enforce protocol separation at the firewall on both HA nodes:
- iSCSI (3260/tcp): storage-client subnet (192.168.20.0/24) only
- NFS (111,2049,20048 tcp+udp): LAN subnet (192.168.2.0/24) only
- Cluster subnet (192.168.10.224/29) accepted wholesale (DRBD+Corosync)
Moves from allowedTCPPorts/allowedUDPPorts to source-restricted extraCommands
rules on the nixos-fw chain.
NFS exports reduced to LAN-only (drop haClientCidr lines from mkNfsExports).
Storage-client network clients use iSCSI only; no NFS on VLAN 20.
All HA script VIP/storage IP defaults updated to match.

Infrastructure changes already applied to pve1:
- vmbr2 internal bridge created (192.168.5.0/24, no physical uplink)
- VM 200 (ha-server-1): net2 added → vmbr2 (ens20)
- VM 201 (ha-server-2): net2 added → vmbr2 (ens20)
- CT 105 (docker): net1 added → vmbr2 (eth1)
- VM 101 (server): net1 added → vmbr2 (ens19) — needs reboot to activate
NixOS config (deploy to ha nodes to complete; docker/server at cutover):
- ha-server-{1,2}/host.nix: ens20 with 192.168.5.{228,227}/24
- docker/host.nix: eth1 with 192.168.5.225/24
- server/host.nix: ens19 with 192.168.5.226/24
- cluster-config.nix: corosync ring1 on LAN IPs as backup heartbeat path
- cluster-config.nix: allow haClientCidr (192.168.5.0/24) in iptables
- ha-server.nix: NFS exports now allow both lanCidr and haClientCidr
- VIP moves from 192.168.2.229 (vmbr0/LAN) to 192.168.5.229 (vmbr2)
- iSCSI portal to be rebound from [::0] to 192.168.5.229 at cutover
variables.nix: haStorageCidr corrected to 192.168.4.224/29; new vars:
vmStorageClientInterface, lxcStorageInterface, haServer{1,2}ClientIp,
dockerStorageIp, serverStorageIp, haClientCidr/PrefixLength; haServerVip
updated to 192.168.5.229.

crm_mon 2.x formats the Promoted line as " * Promoted: [ node ]" — the
asterisk bullet means the previous grep -E '^\s*(Promoted|Masters):' never
matched, so active-node detection silently returned empty in health.sh,
failover.sh, and acceptance-tests.sh.
Fix: pipe through grep -v Unpromoted first, then grep -E '(Promoted|Masters):'
without anchoring to start-of-line.
Also: remove the SSH_OPTS=-i ~/.ssh/... variable pattern in health.sh and
failover.sh; tilde is not expanded inside double-quoted strings, so $SSH_OPTS
was passing a literal ~ to SSH. Inline the key path in each function
definition instead (same as acceptance-tests.sh already did).
Also: drop the 2>/dev/null embedded in the crm_mon argument string — the
outer 2>/dev/null on the n1/n2 call already suppresses SSH stderr; the
embedded one was harmless but noisy to reason about.

failover.sh: graceful active→standby resource migration with pre-checks
(DRBD UpToDate/UpToDate, quorum), spinner wait for XFS mount on target,
rollback on timeout, --to/--force/--dry-run/--timeout flags.
health.sh: read-only status panel — node reachability, quorum, DRBD
role/dstate/cs per node, Pacemaker resources, failure history, XFS mount
usage, and service port checks (NFS 2049, iSCSI 3260) via VIP.
