Remember Last Selected Device Emulator Across Sessions

Is your feature request related to a problem? Please describe.
Yes, currently, every time I open a new webview window in vscode-edge-devtools, I have to manually switch to the device emulator I want to use. This process is cumbersome and interrupts the development workflow.

Describe the solution you'd like
I would like vscode-edge-devtools to remember the last selected device emulator (emulatedDevices) across sessions, similar to how Chrome DevTools operates. This feature would significantly enhance the user experience by eliminating the need to repeatedly select the desired emulator for each new webview window.

Describe alternatives you've considered
N/A

Additional context
This enhancement would streamline the development process, especially for developers who frequently test their web applications across different device emulators. Remembering the last selected emulator would reduce repetitive tasks and improve efficiency.

If deemed necessary, I am willing to contribute by submitting a PR to implement this improvement.

Start by locating where the emulatedDevices selection is handled in vscode-edge-devtools and how settings or state are persisted across webview sessions. Confirm the current selection path, then verify that opening a new webview restores the previously selected emulator without requiring manual switching.
