Drop the eval assertion b78190e1 added. It refused every self-signed
gateway host that does not run the store, which is the default hive
shape, and contradicts docs/swarm/secrets.md's supported no-store
deployment. The approved #4921 plan has such a host evaluate and fail
at runtime; `requireServicesIssuer` already exits 1 naming both
options, on the root-fetch branch and before issuing.
The module-eval case that pinned `hiveWithController { }` as refused
now pins it, and a hive-less gateway with no pair, as evaluating with
the unit's refusal in the script. The fixture pairs the assertion
forced into forge-placement, nats-tls and swarm-otel-identity are
reverted.
