…61330) Hive external tables currently apply session time zone day offsets when decoding ORC/Parquet DATE columns. In west time zones such as -06:00, this shifts DATE values by one day earlier, while Spark keeps the original logical date. This PR removes the incorrect time zone day adjustment from Hive DATE decoding paths in ORC and Parquet readers. TIMESTAMP-related time zone handling is unchanged. It also adds: - BE unit coverage for west time zone DATE reads in ORC and Parquet - Hive external regression coverage for UTC and -06:00 reads against the same DATE data Local BE build / regression execution was not run on this machine because the current environment does not support BE compilation or running those tests; pipeline validation is expected to cover execution. Issue Number: N/A Related PR: N/A Problem Summary: - Fix CIR-19660: Hive DATE columns read one day earlier in west time zones - Keep DATE semantics time-zone-independent for ORC/Parquet external reads - Add unit and regression coverage for UTC vs west time zone consistency Fix Hive external table DATE columns being shifted by one day in west time zones when reading ORC/Parquet files. (cherry picked from commit 18e5dda)

What problem does this PR solve?
Fix Hive external table DATE columns being shifted by one day in west time zones when reading ORC/Parquet files.
This backport keeps DATE semantics time-zone-independent for Hive external ORC/Parquet reads and includes the matching unit and regression coverage from the merged master change.
