Inconsistency in auto.offset.reset default between /query and /query-stream

[vcrfxia]

The /query endpoint defaults to auto.offset.reset=latest, while the /query-stream endpoint defaults to auto.offset.reset=earliest. This is confusing because the ksqlDB CLI sends queries to the /query endpoint, while the Java client sends queries to the /query-stream endpoint, so the behavior is inconsistent.

We should update the /query-endpoint to default to auto.offset.reset=latest to be consistent with existing behavior for the ksqlDB CLI.
