When hive partitioning prunes down to a single file, aggregate optimization can request statistics for partition columns that are not present in the parquet file schema. Guard against out-of-bounds column indices instead of asserting, and add a regression test for MAX on a hive date column. Fixes duckdb#25629

…25766) Cherry-pick of #25690 onto `v1.5-variegata`. On 1.5.x, MAX/MIN on a hive partition column still crashes/asserts when file pruning leaves a single parquet file. Hive partition columns can have storage indices outside the parquet file schema. Guard `GetColumnStatistics` and `MinMaxIsExact` instead of asserting on bounds.
