…c#142752) * fix(esql): check per-shard DateFieldType for DocValuesSkipper in SearchContextStats min/max hasDocValuesSkipper was derived once from the first shard's DateFieldType and applied globally via doWithContexts. In mixed environments (TSDB shards with DocValuesSkipper + standard shards with PointValues), calling the wrong API on some shards caused sentinel values (Long.MIN_VALUE/Long.MAX_VALUE) to leak into min/max. Replace doWithContexts with direct per-context iteration so each shard's own DateFieldType determines whether to use DocValuesSkipper or PointValues. This also simplifies the early-return guard by removing the incorrect indexed check that could bail out prematurely in mixed modes.
