Dashboard improvements, bug fixes, and upstream security improvements

This release replaces the old list of countries with an annotated world map, adds relative bars to the tables to help visualize relative stats, and includes several bug fixes and upstream security improvements.

Notably, this is the first Shynet release that was driven entirely by contributors. I (Miles) did not develop any of the features myself—they were all contributed by our fantastic community (shoutout to @CasperVerswijvelt and @haaavk).
