Your whole store's bandwidth

Account-level (no customer header): what all your customers used per day beside what you sold per day, per product, and the ten customers that used the most, over the last days days. gb_used is the meter, gb_sold is GB on paid orders by the day they were paid, gb_total and gb_left are what the measured plans had and still held at the day's last reading; the four are never mixed into one number. unknown_days counts plan-days without a reading. Readings land every 30 minutes, one pass after each plan's own figures are synced. Snake_case like the other account-level doors.
