The metrics store's container gets privateNetwork = true with no
interface but loopback. VictoriaMetrics listens on
unix:/run/swarm-victoriametrics/victoriametrics.sock, a host directory
(root:nginx 0770) bind-mounted into the container, and every vhost
location that forwarded to 127.0.0.1:8428 now forwards to that socket.
The store runs as a static user whose primary group is nginx's gid,
with UMask 0007, so the socket it creates is 0770 group nginx. This
relies on VictoriaMetrics >= 1.153.0 honouring the umask (the locked
nixpkgs ships 1.153.0). nixpkgs' readiness loop curls a TCP URL, so
postStart is replaced with the same loop over --unix-socket.
swarm.victoriametrics.port is removed (nothing binds it any more), with
a mkRemovedOptionModule entry, and dropped from swarm-otel's host
port-collision assertion. The container's resolver unit is dropped:
there is no interface to reach the bridge resolver through, and the
store resolves no names.
The collector scrape, the collector push and Grafana's datasource
already reach the store by its published domain, so they are unchanged.

- swarm.victoriametrics.port: the description states why the listener is
loopback-only instead of pointing "below" at text in another file.
- authelia: the deploy half derives its unit and instance names from
swarm.authelia.unit, so the instance is spelled once, in
swarm-authelia-service.nix.
- authelia: the tokenEndpointAuthMethod and bearerAuthz descriptions name
the obligations the authelia host asserts instead of "below"; the
swarm-authelia.nix header describes that file only.
- module-eval-swarm-otel-core: swarm.otel.audience must contain both store
push URLs the collector's exporters use and request tokens for.

`swarm.victoriametrics` (what the metrics store is to every hive: container
name, domain, port) moves to nix/host-modules/swarm-victoriametrics-service.nix,
together with the only two helpers it reads, `swarmDomain` and `domainBase`.
Everything else -- the `deploy.victoriametrics` options, the whole `config`
block including `containers.swarm-victoriametrics`, the file header and the
helpers only they read -- stays in nix/host-modules/swarm-victoriametrics.nix,
which default.nix now imports alongside the new file.
`hyperhiveCfg` (an alias for `config.services.hyperhive`, not an option) is
read by both halves, so it is duplicated into the service file rather than
shared.
A pure move: option paths, option definitions and config are unchanged
apart from the comment above the `deploy.victoriametrics` options, which now
names the file `swarm.victoriametrics` lives in. Fixtures enabling the store
evaluate to the same host and container toplevel derivations before and
after.
