OHLCV history for a single coin, bucketed to the requested interval across all venues.

Cross-venue OHLCV rollup built from `candle_1m` rows. For each bucket we fold (first open, MAX high, MIN low, last close, SUM quote volume, SUM trade count) across every instrument under this base. Use this when you want a single line for the whole asset class; for venue-specific bars use `/api/v1/candles` with an `exchange` filter.
