Staff report: hide section anchor nav when framed in Civi

The iframe in the Engagement Report tab is sized to fit content, so it
has no internal scroll context. Clicking an anchor link inside it
changes the URL hash but the iframe content doesn't move and the user
has to scroll the outer CiviCRM page manually. Rather than coordinate
cross-frame scroll with the parent, just skip rendering the anchor
strip when framed. Standalone view is unchanged.
