chore: regenerate cordis/client service catalogs for openRouterUsage

The prior openrouter feature commit added the ctx.openRouterUsage Remote
service without a SERVICE_PAGE partition entry or regenerated artifacts, so
the committed api-catalog, slot-catalog, and llm-streaming subsystems docs
were stale and the catalog byte-for-byte gate failed. Map the service to its
documentation page, regenerate all three artifacts, and re-record the
bilingual sidecar.
