FX.121 Admin dashboard shows SuperCad Studio revenue

The /admin dashboard counted SuperCad owners and seats but no dollars: revenue figures read only owned licenses and Team Cloud Plan. Added a "SuperCad Studio revenue, all time" tile, SuperCad rows in the License payments table, and SuperCad in the one daily chart: blue bars = licenses, green bars = SuperCad seats, line = grand total revenue to date (all sales). Test emails left out. Billing::revenue(), payments(), dailyLicenses(). Not in the Licensed users count. Checked against live data (4 purchases, 6 seats, $175; Handybear $150 listed); page not looked at in a browser.
