Multiple ports & per-port model catalogs

Quartermaster can expose several listen ports from one process, each showing a different subset of models - e.g. an 'assistant' port and a separate 'tools/judge' port.

Changing a listener's bind address needs a restart; its model scoping updates live on config save.
