/**
 * Structural regression test for App.tsx WS handler registrations.
 *
 * Guards the 5 onOrgSaved* callbacks that MUST all be registered in the
 * socket-handlers object. A missing one is silent (TypeScript-level the
 * callback is optional) and results in broken UX: earlier bug report
 * "can't switch saved orgs" was caused by the 3 of these being absent.
 *
 * Also guards:
 * - Toast state wiring
 * - useCallback stability for client.org* calls (no inline arrows in
 *   <OrgTab> props)
 *
 * Runs with `tsx` against node:assert/strict — matches repo convention
 * for zero-framework tests.
 *
 * Usage:
 *   tsx opc/plugins/office_ui/frontend_src/App.test.tsx
