docs(cli): correct the core-web overlay's ui-question rationale

The comment claimed `ui-question`'s host half owns the `ask_user_question`
registration. That was true and is the exact mechanism that leaked the tool
past every preset; with the node half emptied, disabling the row is a UI
decision rather than a capability one.
