/**
 * Guards JS → native commerce enum mapping used by the bridge (including New Architecture).
 * Constants must stay aligned with `ProductActionType` / `PromotionActionType` in js/index.tsx.
 *
 * Direct `MPCommerceEventAction` / `MPPromotionAction` tests above validate the table only.
 * JSON → `MPCommerceEvent` tests below exercise the same `+[RCTConvert MPCommerceEvent:]` pipeline
 * used to assemble an `MPCommerceEvent` before `-[MParticle logCommerceEvent:]` (legacy bridge path),
 * including `MPPromotionContainer:` wiring. That catches regressions such as casting JS ints in
 * those helpers instead of calling the mappers. The New Architecture TurboModule `logCommerceEvent`
 * codegen struct path is still not invoked here (would require generated C++ types in this target).
