Returns a validator earnings/profitability summary with aggregated metrics at three levels
(latest round, 1-hour average, 24-hour average), the CC price used, and the estimated traffic
(billing) cost. Net post_traffic figures can be negative when traffic cost exceeds earnings.

Unknown party: This endpoint always returns HTTP 200 — the metrics are derived from

network-wide mining rounds, so an unknown party still yields a populated summary rather than a
404. A malformed party id (not in participant::identifier form) returns HTTP 400.
