Downloads a ZIP with one CSV per report (overview, trend, pages, entry/exit
pages, sources, referrers, countries, devices, funnel). Export button lives
next to the period selector and picks up the current period and any active
filters using a JS hook + JS.set_attribute, so the downloaded data always
matches what's on screen.
