Rationale for this change
The temporal Parquet fuzz tests cover date columns in scalar, array and struct form but omit maps.

Add a
map<date,date>column to the existing test matrix. Compare maps withoutORDER BYand assert native scans where Comet is enabled. Preserve the Spark answer checks when INT96 timestamp conversion disables Comet.How are these changes tested?
All nine temporal variants pass locally on Spark 4.1.3. Fork CI passed, including the scans suites on Spark 3.4–4.2 and macOS Spark 4.0.
