Add a consistency report across IPAM, DNS and servers

New Consistency page listing where the three places this app records
what lives at an address disagree:
- Address conflicts: the same address reported by more than one server.
- DNS out of date: a record named after a server (its hostname, or its
  short name) that points at an address the server doesn't report.
- IPAM out of date: an entry labelled with a server's name at an
  address the server doesn't report.
- Not in IPAM: addresses a server reports or DNS points at that IPAM
  doesn't list, merged into one finding per address, with a one-click
  "Add to IPAM" that pre-fills a label.
- No DNS record: server LAN addresses no cached A/AAAA record resolves to.

It compares data the app already holds and fetches nothing when opened,
so the page states how many servers had reported addresses and how many
DNS zones are synced (and how old the oldest sync is) -- DNS records are
only cached for zones that have been synced, and a report that silently
treated missing data as "no records" would mislead.

Rules chosen to keep it from crying wolf:
- Only private addresses are compared; public DNS records aren't expected
  to be in IPAM.
- Servers with no reported addresses are never judged.
- Agents report IPv4 only, so records are only compared within an address
  family (an AAAA record isn't "stale" for lacking an IPv6 address).
- Docker bridge networks (172.16/12) are ignored: shared ones aren't
  conflicts, and they aren't listed unless someone put them in DNS.
- Tailscale addresses don't need DNS records (MagicDNS), and IPAM entries
  kept current by the Tailscale/Proxmox syncs aren't second-guessed.

Findings anyone has decided are fine can be ignored (operators) with a
reason. An ignore is keyed on the finding's stable identity so it stays
ignored across runs, its stored text comes from the finding rather than
the request, and it is marked "no longer occurring" once the condition
goes away. Ignore/restore are audit-logged.

New table consistency_ignores (migration 0012). portScan's private-address
helper is now exported and shared.

Verified with 36 checks (each rule and its exclusions, address-family and
case/trailing-dot handling, IPv6 case, ordering, stable keys, the report
route including a garbled agent report, source counts, ignore/unignore
rules and audit entries) and by driving the page against the real routers
in a browser: Add to IPAM actually created the entry, ignore and restore,
severity filter, "show all", the viewer view, and narrow-width layout
(which found and fixed a squeezed badge and clipped buttons). Real dev
database mtime untouched.

**Consistency** — a report of where IPAM, DNS and your servers disagree about
an address: the same address on two servers, a DNS record named after a server
that points somewhere it isn't, an IPAM entry labelled with a server's name at
the wrong address, addresses in use that IPAM doesn't list (with an "Add to
IPAM" button), and server addresses no DNS record points at. It only compares
data the app already holds — nothing is fetched when you open it — so it says how
many servers reported addresses and how fresh the synced DNS zones are. Only
private addresses are compared; Docker bridge networks are left out; anything
that's fine on purpose can be ignored with a reason, and stays ignored.
**Domains** — when each domain registration expires, read from the registry
itself. The domains behind your DNS zones are picked up automatically (a zone
like `lab.example.se` resolves to the `example.se` registration that actually
