[APAM-653] Bind analytics framework info for React Native

[weiping-awx]

Summary

• Adds framework: "rn" to analytics common data on both iOS and Android so analytics events are tagged with the correct integration framework
• iOS: Calls AWXAnalyticsLogger.shared.bindExtraCommonData in initialize
• Android: Calls AnalyticsLogger.initialize + updateExtraCommonData in initialize, after AirwallexStarter.initialize, to ensure the tracker exists before any payment flow

Test plan

• Run iOS example app, trigger a payment flow, verify analytics events contain framework: "rn"
• Run Android example app, trigger a payment flow, verify analytics events contain framework: "rn"
• Verify all payment flow paths (entire, card, Apple Pay/Google Pay, card details, consent) include the framework tag
