fix(native, ios): fixed null responseIdentifier crash

[malandr2]

Description

Fix: [iOS] Prevent potential nil-key crashes in Native Ad module
This PR hardens the Native Module against potential crashes caused by inserting nil values into an NSMutableDictionary.

• load: Method:

  • Added a nil check. If responseId is nil, we now reject the promise with an error instead of crashing the app when trying to set the value in _adHolders. Now matches Android implementation.

• destroy: Method:

  • Added a nil check before calling removeObjectForKey: to prevent an NSInvalidArgumentException.

• emitAdEvent:withData: Method:

  • Updated to use responseId ?: [NSNull null] to match the safe handling already used for responseId in the code.
  • Made the ad event a nonnull parameter.

Release Summary

Resolving crash NSInvalidArgumentException: *** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[1]
