fix(web): React 19 compatibility and type safety for findNodeHandle

[YevheniiKotyrlo]

Summary

Fixes React 19 compatibility issue and improves type safety in the web findNodeHandle utility.

Problem

React 19 Crash (#2366)

React 19 removed findHostInstance_DEPRECATED and changed when findNodeHandle can return null. With Expo SDK 53+ and React 19, the function crashes when componentOrHandle is null or undefined during component lifecycle transitions (mount/unmount).

Web Platform Crash (#2237)

On web, accessing componentOrHandle.getNativeScrollRef() or componentOrHandle._scrollRef without null checks can crash when the component is unmounted or during hot reload.

Type Safety

The existing code used @ts-ignore to access undocumented React Native scroll component internals, hiding potential type errors.

Solution

1. Early null check - Return null immediately if componentOrHandle is nullish, preventing crashes in React 19

2. Proper TypeScript interface - Replace @ts-ignore with a documented type bridge:

   interface ScrollComponentInternals {
     getNativeScrollRef?: () => NodeHandle | null;
     _scrollRef?: NodeHandle | null;
   }

3. Runtime type checking - Use typeof scrollable.getNativeScrollRef === 'function' before calling, rather than relying on try/catch for flow control

4. Explicit return type - Add proper return type annotation for better type inference
