fix: Unable to Srub on Line Chart in New RN Arch

[shreypdev]

What changed? Why?

Consumer apps migrating to React Native's new architecture experienced broken chart scrubbing due to an outdated version of react-native-gesture-handler.

Changes:

• Upgrade react-native-gesture-handler: 2.16.2 → 2.24.0
• Add useEvent mock for test compatibility
• Remove unused patch file

PR with new arch #153

Why this bump is required

We encountered an issue where gesture handlers such as <GestureDetector gesture={longPressGesture}> were not correctly recognized or triggered on apps using the React Native New Architecture (Fabric) when using version 2.16.2. After upgrading to 2.24.0, gestures started working correctly under the new architecture.

Technical Reason

• Full Fabric support (React Native New Architecture) began in versions after 2.3.0, but many critical bug fixes and improvements were introduced after 2.16.2 and up to 2.24.0.
• The core fixes include major refactors in gesture detector internals, virtual detectors, and root view management to support Fabric.
  • Notable PRs merged in this range:
    • One detector to rule them all
    • Virtual detector native gestures
    • Throw error when detectors are not placed inside GestureHandlerRootView
    • Multiple Android/iOS bug fixes and cleanups for gesture registration
  • These address issues where gestures did not register on Fabric surfaces, and improve Fabric integration, event delivery, and root view detection.
