[🐛] `NativeAd` paid event type exposes `currencyCode`, but the bridge sends `currency`

[sanjaysargam]

What happened?

Summary

NativeAd.addAdEventListener(NativeAdEventType.PAID, ...) exposes a payload type
with currencyCode, but both native implementations emit the JavaScript payload
key as currency.

TypeScript accepts payload.currencyCode, but that property is undefined at
runtime. The actual value is available at payload.currency.

Evidence

The NativeAd TypeScript payload declares currencyCode:

export type NativeAdPaidEventPayload = {
  value: number;
  precision: number;
  currencyCode: string;
};
