Pull Request Overview

This PR modernizes the Jest test infrastructure to support React Native TurboModules while maintaining backward compatibility with legacy Native Modules. The changes update mocking strategies, refactor test assertions, and upgrade Babel dependencies for better TypeScript support.

Key changes:

• Consolidated React Native module mocking to support both TurboModules and legacy Native Modules
• Refactored event listener tests from generic on/off pattern to specific event handler tests
• Removed sendEvent test coverage as this method doesn't exist in the native implementation
• Added TypeScript preset to Babel configuration and updated related dependencies
