Busiest hours and the heatmap count the different players on T or CT in
each hour, open segments included, instead of averaging player-hours, so
one player for part of an hour is 1, not 0.38. Their descriptions end in
the span covered (Last 30 days, or Since <date>). Side-by-side chart panels
match heights, and Players per day notes its busiest day.
Dropped the page descriptions on Bans, Gags & mutes, Staff and Playtime,
and the Verified badges on the staff Overview scoreboard and drawer header;
the Verification page and the drawer's Verification section still show it.
The GroupVerify DB test now checks the staff drawer, since the public site
says nothing about verification.
