/**
 * Probe spec: drives the wizard, opens File menu, clicks Open, then dumps
 * everything we need to know about the wxFileDialog state — what frame paints,
 * what directory the dialog starts in, what list items are registered, what
 * the OK/Cancel button labels are, and which MEMFS directories exist.
 *
 * Output:
 *   tests/logs/kicad/load-pcb-probe/<test-name>.log       (everything via console)
 *   tests/test-results/probe-*.png                        (screenshots)
 *
 * This is a one-shot investigation, not a regression test. It always passes;
 * the value is the captured state.
