feat(ha): implement clan vars and fully encrypt all HA secrets

- Run sync-host-keys.sh for proxmox-ha-server-{1,2}: generates SSH host key pairs in vars/per-machine/, registers age anchors in .sops.yaml, adds both hosts as recipients for common.yaml, ha-corosync-authkey, and per-host secrets/keytab files - Re-encrypt secrets/common.yaml with both new host keys - Convert all stub secrets to real sops-encrypted files: secrets/ha-server-{1,2}.yaml (YAML, beszel-token = PLACEHOLDER) secrets/ha-server-{1,2}.keytab (binary, stub text encrypted) secrets/ha-corosync-authkey (binary, stub text encrypted) - Add scripts/ha/deploy.sh: full lifecycle script (bridge setup, VM creation, DRBD disk + storage NIC attachment, boot wait, cluster-init, acceptance tests, --destroy) Bootstrap order (operator runs these before first deploy): 1. bash scripts/ha/deploy.sh # deploys, tests # Post-deploy secret replacement: 2. sops secrets/ha-server-{1,2}.yaml (set real beszel-token) 3. bash scripts/ipa/create-nixos-ipa-host-account.sh --ip 192.168.2.228 ha-server-1 4. bash scripts/ipa/create-nixos-ipa-host-account.sh --ip 192.168.2.227 ha-server-2 5. Set services.beszel.agent.environment.KEY in host.nix after hub pairing 6. nixos-rebuild switch on both nodes to pick up real secrets Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HaH1cSGvhogRP5ExoF6nD8

+# deploy.sh — Full lifecycle management for the HA file-server cluster.
+#
+# Handles everything from zero (no VMs, no secrets) through a running,
+# tested cluster, and optionally tears it back down.
+#
+# Usage:
+#   scripts/ha/deploy.sh [options]
+#   scripts/ha/deploy.sh --destroy [options]
+#
+# Phases (all run by default; skip any with --skip-*):
+#   1. ensure-bridge   Create storage bridge (vmbr1) on the Proxmox node if absent.
+#   2. sync-keys       Generate SSH host keys and register age keys for both nodes.
+#   3. create-vms      Build disk images and create both VMs via create-proxmox-resource.sh.
+#   4. add-hardware    Attach storage NIC (vmbr1) and DRBD data disk to each VM.
+#   5. boot-wait       Start VMs, wait for SSH on both nodes.
+#   6. cluster-init    Form the cluster: DRBD, corosync, Pacemaker, NFS, VIP.
+#                      Also encrypts the generated corosync authkey into the repo.
+#   7. run-tests       Run acceptance tests (T1–T7).
+#
+# Options:
+#   --node <host>            Proxmox host to deploy on (default: pve1.sweet.home)
+#   --vmid1 <n>              VMID for ha-server-1 (default: 200)
+#   --vmid2 <n>              VMID for ha-server-2 (default: 201)
+#   --storage <pool>         Proxmox storage pool (default: local-zfs)
+#   --storage-bridge <br>    Bridge for HA storage network (default: vmbr1)
+#   --drbd-disk-gb <n>       DRBD data disk size in GB (default: 32)
+#   --memory <MB>            RAM per node (default: 4096)
+#   --cores <n>              vCPUs per node (default: 4)
+#   --skip-ensure-bridge     Skip storage bridge creation/check
+#   --skip-sync-keys         Skip sync-host-keys.sh (clan vars already exist)
+#   --skip-create-vms        Skip VM creation (VMs already exist)
+#   --skip-add-hardware      Skip net1/scsi1 attachment (already attached)
+#   --skip-boot-wait         Skip boot/SSH wait (VMs already running)
+#   --skip-cluster-init      Skip cluster formation (cluster already configured)
+#   --skip-tests             Skip acceptance tests
+#   --force-rebuild          Pass --force-rebuild to create-proxmox-resource.sh
+#   --destroy                Stop and delete both VMs (skip all other phases)
+#   --dry-run                Print what would run without executing
+#   -h|--help                Show this message
+#
+# Prerequisites:
+#   - SSH access to the Proxmox node as $PROXMOX_SSH_USER (wayne).
+#   - sops age key in the standard location (used by sync-host-keys.sh).
+#   - For --skip-sync-keys: clan vars already in vars/per-machine/proxmox-ha-server-{1,2}/.
+#   - For full tests: secrets/common.yaml decryptable on both nodes (run
+#     `sops updatekeys secrets/common.yaml` after sync-keys).
