Improve fuzz counts

Improve fuzz counts

This replaces the "Always scan through all of the GCS files every N minutes to count fuzzes" with something that 1) caches results of things that won't change and 2) is correct.

The previous fuzz counts were often wrong (what does -34 new bad fuzzes mean?) and were slow.

This also includes a few expand-related UI glitch fixes and replaces the "new grey fuzz" count with
"new regressions", which should be more useful.
