Adds services.hyperhive.swarm.victorialogs.domain and a gateway vhost
gated by the same auth_request check against authelia that swarm-uis
own vhost uses (same swarmAuthRequest shape, copied not shared - see
the file top comment for why). The stores own listener stays
loopback-only and unauthenticated exactly as before; the collector
still writes to it directly, never through this vhost, so this only
adds a new authenticated read path.
Registers the new domain in swarm.nixs serviceDomains so the
swarm-services sub-CA issues for it (a missed entry silently falls
back to the hive leaf, which cannot cover a name under a different
apex - swarm.nixs own comment on that list documents the incident
this caused before).
Verified with a throwaway module-eval (same technique as the flake
module-eval check): vhost only exists when victorialogs.enable is
set, forceSSL/no addSSL, both locations present, domain correctly
registered/absent from serviceDomains, links entry present.
An agent can verify that a unit was launched and never that it is
working: container journals are not reachable, so a diagnosis stops at
the first broken component -- which is precisely the component whose own
instrument is least likely to be legible. This is the store half of
collecting logs centrally so the question becomes answerable.
Mirrors swarm-victoriametrics deliberately: same container shape, same
loopback pin, same self-scrape arrangement. Two differences, both
intentional.
No gateway vhost. VictoriaLogs' ingest and query endpoints carry no
authentication of their own, exactly like the metrics store's -- and the
metrics store IS published under a resolvable name, which is an open
question rather than a settled design. Publishing this one the same way
would repeat that before the first instance is decided.
Retention defaults to 30d against the metrics store's 5y. Logs are
orders of magnitude larger per unit of time and their value decays much
faster: a log line answers what happened during an incident, a metric
answers whether this is worse than last quarter.
Not wired into enableRequiredServices yet -- that lands with the
collector pipeline, so we do not start a store nothing writes to.
