feat: update SDK versions and rewrite example app with comprehensive test suite

Updated native SDK dependencies:
- iOS: VerisoulSDK v0.4.57 → v0.4.63-beta.3
- Android: verisoul:android v0.4.59-beta → v0.4.60-beta.0

Completely reimplemented example app to match React Native SDK test suite:
- Created test_harness.dart with comprehensive testing functionality
  - Repeat Test: Sequential or parallel session ID requests with configurable reinit
  - Chaos Test: Concurrent workers with random delays to stress-test SDK
  - Results tracking with success/failure counts and latency metrics

- Built results_view.dart with detailed test analytics
  - Success rate percentage with color-coded indicators
  - Latency statistics (average, min, max)
  - Beautiful Material Design UI matching React Native version

- Redesigned main.dart with modern test suite interface
  - Clean, intuitive UI with emoji icons
  - Configurable test parameters (rounds, reinit interval, parallel mode)
  - Real-time test execution with loading indicators
  - Modal results presentation

- Added http dependency for API authentication calls

The example app now provides a robust testing environment for validating
SDK session management, reinitialize behavior, and concurrent request handling
across both iOS and Android platforms.
