## What changes were proposed in this pull request?
The Capacity page showed the datanode sections as loading based on the
pending-deletion scan status. That status only changed to **FINISHED** through
the auto-refresh polling loop.
The problem was that if Auto Refresh was turned off while a scan was still
running, polling stopped completely. As a result, the scan status never updated
to **FINISHED** on the page, even though it had completed on the backend,
leaving the datanode sections stuck in a loading state.
This change separates scan completion polling from the Auto Refresh setting.
While a scan is in progress, the page now continues polling every 5 seconds and
refreshes until the scan reaches **FINISHED**, regardless of whether Auto
Refresh is enabled. Once the scan is complete, the Auto Refresh toggle resumes
controlling the normal periodic refresh behavior. A separate `setInterval`
handles polling when Auto Refresh is off, and a ref ensures it always calls the
latest refresh function instead of an outdated one.
A new Capacity test has also been added to verify this behavior. With Auto
Refresh turned off, the test confirms that polling continues while the scan is
in progress (`IN_PROGRESS → IN_PROGRESS → FINISHED`) and stops once the scan
finishes.
