Splits the analytics panel into Traffic / Engagement / System tabs so
episode plays, engagement metrics, and contact/study data are no longer
buried under the visitor log.
Fixes a bug where topCountries, topStates, topCities, device breakdown,
and referrers were computed from only the 100 most-recent visitor rows
instead of all rows in the selected range — causing older geographic data
(e.g. visits from India, Texas, Georgia) to silently disappear from the
aggregate totals.
