authelia takes the first matching rule, and a rule with a `subject` does
not match a subject outside it. The swarm domain's and the bao UI's
`group:admins` rules had nothing after them, so an account in no group
skipped them and landed on `default_policy = one_factor`: any
authenticated account reached the swarm UI, its `/api/` (by cookie or by
bearer) and the bao UI.
Each of the two group rules is now an `operatorsOnly` pair: the group
allow, then a subject-less `deny` for the same domain, the shape
`collectorOnly` already gives the collector's metrics rules.
`default_policy` stays `one_factor`, which the forge and chat rely on.
module-eval-swarm-otel-identity gains two cases on `allLocal`: an
account in no group is refused the swarm domain (four paths) and the bao
UI while `group:admins` passes and the forge stays open; and a
predicate, `autheliaSubjectRulesClosed` in lib.nix, holds over the
rendered list: every subject-scoped allow is closed by a later
subject-less `deny` on its domain with no subject-less allow in between,
and nothing follows a domain-wide `deny` on its domain.
