The controller's queue coordinates were gated on `autheliaCfg.enable &&
natsCfg.enable` -- i.e. on this host running both. Split the hosts and
the whole env block vanished, which the daemon's own rule reads as "no
queue configured": it started cleanly, served /api/hives, and silently
never connected or published.
Make the coordinates options instead, defaulted to the co-located values
so nobody types a path they didn't need, and assert each one so a split
deployment fails at eval naming the option rather than running blind.
The queue is required for a controller -- /api/hives/status reads the KV
-- but co-location with it is not.
