Build Paginated Shipment Response for System API
Veridian Logistics exposes a Shipments System API consumed by internal Process APIs and third-party logistics partners. When a paginated query returns results from Oracle DB, the raw JDBC output carries uppercase column names and a full datetime string — none of which match the API contract. This challenge asks you to rename every field, compute the pagination envelope from the result set, and read page metadata from the HTTP request attributes preserved earlier in the flow.
