Which issue does this PR close?
Rationale for this change
This PR adds a constructor StatisticsConverter::from_column_index that bypasses schema resolution and accepts a pre-resolved leaf column index directly
Datafusion's pruning predicate system needs stats for struct fields to support predicate pushdown on expressions like
WHERE my_struct.field > 67. Datafusion already resolves struct fields to Parquet leaf indices elsewhere, but has no way to pass that index to StatisticsConverter
