Aggregate Payment Data for JDBC Bulk Insert

Transform flat payment records into aggregated reporting rows for a JDBC Bulk Insert. You will practice using `groupBy` to partition data, `sumBy` from `dw::core::Arrays` to compute totals, and calculating percentage shares against an overall total, outputting a List of Maps required by the database connector.
