feat: publish unblended AI-plan effectiveness series

Report booked cost, entitlement, token coverage, and work as three
series: work per measured token, work per measured+estimated token,
and work per euro. Months below 50% coverage are unfit for token
trends. There is no blended efficiency number.

ranked cheaper on a token series; there is no blended efficiency
field.
