Three more user-triggered status messages that updated silently for screen-reader users:
- clipStatus — clip download progress/result text below the URL input on the Clips tab
- eventsViewerStatus — loading/error message inside the events viewer modal
- chatViewerStatus — loading/error message + filter result count inside the chat viewer modal
All three get role="status" + aria-live="polite". Same reasoning as 4.6.153/154 — the user explicitly clicks a button or opens a modal, then the result fills in asynchronously. Without aria-live the announcement was lost.
