- 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.
