Module catalog_display 

Converts raw catalog Arrow batches into display-friendly Arrow batches.

Catalog batches store prices and quantities as scale-16 decimals plus schema metadata. This module preserves the raw catalog query path while converting the values to named Float64 columns suitable for PyArrow/Polars. Migrate legacy catalog files before requesting display output.
