docs(dns): document DNS zone layout for all three networks
Check NixOS configurations / eval-hosts (push) Failing after 14m52s

Adds a DNS Zones section to ip-addressing.md covering the three FreeIPA
zones (sweet.home / cluster.home / storage.home) with all A records and PTR
records as configured. Updates Stage 6 in network-cutover.md to reference
nfs.storage.home by DNS name rather than the raw VIP IP, and marks DNS as a
completed prerequisite for the HA storage cutover.

## Stage 6 — HA storage cutover (docker NFS remount)

> - DNS configured: `storage.home` zone populated, `nfs.storage.home` resolves to 192.168.20.229 ✓
> - docker CT has eth1 on vmbr2 (`docker.storage.home` → 192.168.20.225) ✓
> - Final rsync from server.sweet.home to `/srv/ha-data` complete before step 6b
docker.sweet.home currently NFS-mounts its persistent volumes from `server.sweet.home`
(`192.168.2.226:/tank/docker/...`). This stage moves those mounts to the HA cluster's

### 6b. Update docker NixOS config to mount from vip-storage
In `hosts/docker/host.nix` (or wherever the NFS mount fileSystems are declared), change
the NFS server from `server.sweet.home` / `192.168.2.226` to `192.168.20.229`:

```
Using the DNS name (`nfs.storage.home`) rather than the VIP IP means the mount
config survives a future VIP renumber without touching the NixOS config.
Repeat for all four docker shares (`config`, `databases`, `volumes`, `nextcloud-data`).
Then rebuild docker:
