fix(desktop): wait for channel status to settle before returning

The listStates IPC handler now waits for any "starting" status to
settle (max 3.5s) before returning, ensuring the UI always gets the
final status (running/error) instead of the transient "starting" state.

Also fixes unused variable lint warning in profile page.
