feat: implement websockets for live job status updates

[Dhara124]

Description

This PR introduces a real-time WebSocket connection to the Synthetic ASR Dashboard to receive live job status updates directly from the backend.

Key Changes

• Integrates 'react-use-websocket' to manage an authenticated WebSocket connection.
• Replaces the previous polling/manual refresh mechanism.
• The React state optimally updates individual job rows as soon as the PAI backend broadcasts a status or progress change (e.g., from \SUBMITTED\ to \PROCESSING, 25% to 50% progressed).
• Dashboard populates instantly upon connection without requiring a page refresh.
