nix: move the remaining service containers onto the swarm-container module

Browse source 
hive-ci, hive-forge, hive-matrix, swarm-authelia, swarm-bao, swarm-grafana,
swarm-nats, swarm-otel and swarm-victorialogs now import
./swarm-container.nix and drop their own copies of the stateVersion,
firewall and resolvconf lines. Each binds privateNetwork once in its
top-level let and passes it to both the host attr and the in-container
option, as swarm-victoriametrics already does.

hive-forge (25.11) and swarm-otel (the host's value) keep their own
stateVersion over the module's mkDefault. hive-ci sets privateNetwork =
true and writesOwnResolvConf = false, which leaves its firewall and
resolvconf on, as before. hive-matrix keeps its useHostResolvConf
override and static resolv.conf; its resolvconf mkForce now comes from
the module default.

Every container's system.build.toplevel drvPath and host-side attrs
evaluate identical to the parent commit.

module-eval-swarm-services-switch gains a fixture with all ten service
containers and checks that each one's in-container privateNetwork equals
its host-side value, that the nine on the host netns run no firewall or
resolvconf, that hive-ci keeps both, and that hive-forge keeps its pinned
stateVersion.
