refactor(showcase): rename In-Chat HITL rows to name the hook API

gen-ui-interrupt and hitl-in-chat both render an interactive time-picker
inline in the chat, but via different API layers:

- gen-ui-interrupt -> useInterrupt (low-level primitive)
- hitl-in-chat -> useHumanInTheLoop (ergonomic wrapper)

Rename to make the dashboard row label reflect the API distinction.
