Fix Firebolt Q36-Q42 Parquet date filters

[vogelsgesang]

Firebolt's Q36–Q42 used incorrect epoch-day constants.

• Firebolt filtered 16617..16647, meaning July 2015.
• The dataset spans 15888..15917—July 2013.

Therefore, Firebolt returned empty results quickly via Parquet metadata pruning.

This commit uses the dataset's actual epoch-day ranges, so Q36-Q42 process the intended July 2013 rows instead of returning empty results.
