The DownloadIndicator in Layout.jsx now queries discovery-status and shows
discovery progress the same way it shows active downloads and channel tasks:
- Spinning icon appears in the navbar when discovery is running
- Hover popover shows "Discovering channels" with X/Y count and a progress bar
- Polls every 10 s while running, 60 s when idle
- Primary label priority: download % > task phase > discovery X/Y
Discovery page header simplified: progress bar and verbose status removed
since the top-bar indicator now handles it. "Find more" button still
disables while running.
