This reduces the GraphQL polling overhead in the on-demand scans page
by...
* ...including an ETag header in the query to prevent hitting the
  database on every request.
* ...putting the query behind a visibility check to pause the polling
  when the browser tab is not visible.
* ...increasing the polling interval from 1 to 3 seconds.
