Update PostHog import to use React hook (#7135)

# Update PostHog import to use React hook

This PR updates the PostHog implementation in the `useTrack` hook to use the React-specific hook from PostHog instead of the direct import. The changes include:

- Replaced the direct import of `posthog` with `usePostHog` from `posthog-js/react`
- Added the PostHog instance as a dependency to the `useCallback` hook
- Added a null check before calling `posthog.capture()` to handle cases where PostHog might not be initialized

These changes ensure proper React integration with PostHog and prevent potential issues with the hook's dependency array.
