Note

Low Risk
Version-only dependency and package bump with no bridge or JS changes; behavior follows whatever is in Helium 4.5.2 at install time.

Overview
Automated release that pulls in Helium iOS (helium-swift) 4.5.2 for React Native consumers via CocoaPods.

The PaywallSdkReactNative.podspec Helium dependency moves from 4.3.0 to 4.5.2, and package.json is patch-bumped to 3.0.24 so the podspec version tag stays aligned with the npm package. No TypeScript or native bridge code changes in this diff.
