Yesterday and last-7-days panels, the most and least efficient campaign by
cost per lead, and a per-campaign table.
Both windows end yesterday, matching the API: today's figures are partial
and would make every morning read as a collapse in spend.
Costs render as a dash rather than zero when there is nothing to divide
by. A campaign with no leads yet has no cost per lead, and zero would read
as "free".
