The current tracking is wrong for several reasons. Mainly because
of a race condition if the Popups extension fininshed loading
before the Cite tracking script is executed. But further more
wgPopupsReferencePreviews was not a good choice to see if the user
sees previews or not.
The logging now uses the monoschema and only checks for enabled
previews when the click events are fired. The chances that Popups
finished initilizing then are much higher then. We still can see
if the init is not finished and the variable not set though.
Also we won't track the overall pageviews in here but use the
generic pageview_hourly from the data lake instead.

This code is typically not executed on special pages and such, so we
assume the isArticle check doesn't make much of a difference. The main
difference we are aware of is that this will exclude previews.

There are so few users with this configuration that we need to stop
sampling in order to get data. Sampling is still in effect for
"baseline" users with the feature disabled.
We use separate schemas to simplify analytics on the two populations.

Collect EventLogging metrics for footnote and reference link
interactions, so that we can compare behavior with and without
Reference Previews enabled.
This tracking will be reverted once analysis is complete.
A mostly arbitrary sample rate of 1/1000 is hardcoded here. This is
loosely based on the latest tuning of Popups sampling at 1/100,
divided by a conservative factor of 10 to ensure headroom.
The sample is skewed by skipping clients without sendBeacon support,
but we're avoiding the mw.track synchronous fallback, which injects an
image tag and introduces lag any time the user clicks external links
in the references.
