Refactor: Extract track streaming status to custom hook

[Aashuti-Tech-Trek]

This PR addresses two TODO comments in react/features/connection-indicator/components/web/ConnectionIndicatorIcon.tsx by extracting the track streaming status listeners into a clean, reusable React custom hook. Currently, the ConnectionIndicatorIcon component manually listens to JitsiTrackEvents. TRACK_STREAMING_STATUS_CHANGED and dispatches to the Redux store via an inline useEffect. The original authors explicitly noted this should be rewritten into a standalone hook that maintains a local status reference.

Changes made

• Created a new useTrackStreamingStatus(track) custom hook inside react/features/connection-indicator/hooks.ts .
• Refactored ConnectionIndicatorIcon.tsx to utilize the new hook, drastically simplifying the component's internal logic and reducing its dependency on manual event listener teardowns.
• Verified that the UI continues to successfully display the correct real-time track stats with zero visual regressions.

Why this change

• Implements a requested architectural cleanup left behind by previous maintainers (TODO).
• Reduces technical debt and component complexity.
• Promotes reusability for any future components that need to respond to stream status changes.
• Impact Internal refactor only.
• No visual UI changes.
• npm run tsc:web passes with 0 errors.
