A month's figures for bookings that start in the month on the org's clock: confirmed bookings going ahead, their guests and revenue_cents (what they're booked for; a cancelled booking counts nothing), no-shows and check-ins among them, live holds and cancellations; then by_offering (most revenue first, with a class's seats offered and how full they were) and by_source (where bookings came from). Counted by the database, so they hold at any volume
