[fix][grunt][extension] Users can open multiple instances of a single api endpoint history Saved.

Users should be able to open only one, if they click again they should be taken to the opened webview if open or launch the webview just once. At the moment you can create multiple.

Locate the Grunt extension code that handles saved API endpoint history and opens the webview. Start by tracing the click handler, then verify that repeated clicks focus an already-open webview or launch it only once, without creating duplicate instances.
