Subject: Break down purchase receipts by cost/commission, harden XML
 validation and state I/O

Adds a full pre-load validation pass for GM XML seeds (ids, names,
options, commission, LMSR liquidity), replaces IO.print with
System.out, and surfaces detailed error messages across load/save
commands instead of generic failures.
