/v1/historical-dilution Back Online & In-Play Filtering for Dilution Data

Re-enabled endpoints

/v1/historical-dilution is live in production. The endpoint was temporarily returning 503 endpoint_disabled while we validated the backing dataset.

/v1/dilution-data: new show_in_play query parameter. When show_in_play=true, the response is filtered to instruments with material remaining size (>100k) AND either strike ≤ 3× current market price OR variable-rate price protection. Default false preserves prior behavior (all rows returned, with the computed show_in_play flag on each).
