nix: run the forge on one host per swarm (deploy.forgejo.enable)

Every hive with hyperhive enabled ran its own hive-forge container, and
its gateway answered forge.<swarm> with its own bridge IP, so on a
multi-host swarm each hive talked to its own forge.

deploy.forgejo.enable defaults to false and allSwarmServices sets it with
mkDefault, like authelia and bao; singleHostSwarm gets it through that.
The forge's OIDC client moves to a glue module gated on authelia, so a
split authelia/forge swarm still registers it. CI now requires the forge
on the same host, and the controller's forgeTokenFile defaults to null
where the forge is not.

The container runs only on the swarm's forge host

[`../swarm/services.md`](../swarm/services.md)). Every other hive
reaches that host's gateway by `forge.<swarm-domain>`.
