fix: update Customer.io iOS SDK to 4.7.4

[github-actions]

Summary

• update the packaged Customer.io iOS SDK constraint from 4.7.2 to released version 4.7.4
• keep the Live Activity widget rendering pods on the same 4.7.4 version
• use CocoaPods release versions only; no branch, revision, or cross-repository source lock

Why

4.7.4 includes the notification-center delegate composition fix needed for apps that combine Customer.io with another push provider. This is a native dependency update only; the React Native API is unchanged.

Release impact

Intentional React Native patch release. The fix: title ensures customers can actually receive the 4.7.4 dependency through a new wrapper version.

Validation

• CocoaPods trunk contains CustomerIO, CustomerIOLiveActivitiesTemplates, and CustomerIOLiveActivitiesAttributes 4.7.4
• TypeScript compilation passed
• ESLint passed
• npm package build and dry-run passed
• hosted coverage includes API, lint, TypeScript, package, APN, FCM, and Android sample-build checks; see the PR checks for current exact-head status

Note

Low Risk
Version-only native dependency bump with no JS API or logic changes; risk is limited to CocoaPods resolution and native SDK behavior in 4.7.4.

Overview
Bumps the packaged Customer.io iOS native SDK from 4.7.2 to 4.7.4 so CocoaPods consumers pick up the release (including the notification-center delegate composition fix when Customer.io is used alongside another push provider).

Updates cioNativeiOSSdkVersion in package.json, which drives the main and rich-push podspecs, and aligns the sample app Live Activity widget pods (CustomerIOLiveActivitiesTemplates / CustomerIOLiveActivitiesAttributes) to the same version. No React Native JS/TS API changes—dependency pins only.
