Returns a daily rewards time series for a given party, one entry per day in the window
(oldest first). Days with no rewards are included with zeroed values, so the series is
dense across the whole window.

If no explicit date range is supplied, the API applies a default trailing 30-day window.

This endpoint supports a maximum 30-day window per request.

Unknown party: A well-formed party with no rewards is not an error — the API

returns HTTP 200 with a zero-filled days series. A malformed party id (not in
participant::identifier form) returns HTTP 400, and a window wider than 30 days returns HTTP 400.
