feat: implement app tracking transparency

[dargmuesli]

This pull request adds support for Apple's App Tracking Transparency (ATT) framework, allowing the app to request tracking authorization, check the current status, and retrieve the IDFA (Identifier for Advertisers) in a privacy-compliant way. It introduces a dedicated manager for ATT logic, updates the permissions in the app's Info.plist, and connects these features to the web view via new JavaScript message handlers.

Pull request overview

This pull request implements Apple's App Tracking Transparency (ATT) framework to allow the app to request user permission for tracking, check the current tracking authorization status, and retrieve the IDFA (Identifier for Advertisers) in compliance with Apple's privacy requirements. The implementation follows the iOS 14+ ATT requirements.

Changes:

• Added TrackingTransparencyManager class to encapsulate ATT logic and provide a clean interface for requesting permissions, checking status, and retrieving IDFA
• Registered three new WebKit message handlers (att-request-permission, att-get-status, att-get-idfa) to expose ATT functionality to the web view
• Added NSUserTrackingUsageDescription to Info.plist explaining why the app requests tracking permission
