Fix TPC-H decimal fixtures and log schemas

[bdice]

Summary

• regenerate the tracked SF0.01 TPC-H fixtures with physical INT64 values annotated as DECIMAL(15,2)
• add regression coverage tying the committed Parquet decimals to the static Presto schemas
• log Parquet physical/logical schemas and registered Presto SHOW CREATE TABLE output in CI
• run the fixture regression when benchmark tools, TPC-H fixtures, or TPC-H schemas change

Root cause

The static Presto TPC-H schemas changed to DECIMAL, but the tracked SF0.01 fixtures still contained DuckDB-generated DOUBLE columns. Clean local runs therefore failed even though CI passed with freshly generated decimal data.

Validation

• benchmark_data_tools/.venv/bin/pytest -q benchmark_data_tools/tests: 12 passed
• repository pre-commit hooks: passed
• local GPU run with the exact CI coordinator and worker images: 21/21 TPC-H queries passed in 16.94s
• schema logs confirmed all nine monetary fields are physical INT64 with logical Decimal(precision=15, scale=2), matching registered Presto decimal(15,2) columns
