Timer feature for Auto-Reconnect to websocket

[raunaksarawgi]

When the application loses connection to the Robotics Backend (CommsManager.getInstance() returns null), users must manually click the "Reconnect" button in the StatusBar. Although trivial but this requires constant monitoring and manual intervention.

I have implemented an automatic reconnection timer that starts a 5-minute countdown when the connection is lost, and it will automatically trigger the reconnect function (resetManager()) when the timer expires. It also resets when a manual reconnection is attempted.

Implementation Details-

• Used React's useEffect, useRef, and useState hooks to manage timer state
• The timer starts automatically when the connection is lost
• Clears automatically when the connection is restored
• The button shows the countdown to auto-reconnect

Please review this and if this idea sounds good, then I can raise a PR for the same. I'm attaching a snippet of the changed code for reference.
