Overview

Serializer for JSONB columns that store { integer_key => value } hashes,
typically { item_id => quantity } in Packing#contents.

PostgreSQL JSONB always deserializes object keys as strings. This serializer
normalises them back to integers on load so callers can use integer IDs
naturally (e.g. contents[item.id]) without string/integer fallback hacks.

Handles both shapes the contents column can take:
Hash — single-box { item_id => qty, … }
Array — multi-box [{ item_id => qty }, { item_id => qty }, …]
