Add notice that Element Desktop is running in the background

Your use case

What would you like to do?

Add a notice for desktop users that when clicking the close button on the native app window, the application will still be running in the background.

Why would you like to do it?

Discord received a notice by the CNIL to stop this (article in French, sorry)

It is especially important to do in case of a VoIP call where camera and microphone will still be broadcasted if the app is running in the background

How would you like to achieve it?

I will leave that to competent folks to decide

Have you considered any alternatives?

From what I can tell from the article, the issue was not necessarily that Discord runs in the background, but specifically that it leaves the user connected to calls while in the background. Could someone who uses Element Desktop verify whether we do the same? If closing the window automatically hangs up any calls, then I believe this is less critical for us.

Closing the window just minimises it to tray (if that setting is enabled - Settings > Preferences, not available on macOS) - it doesn't inform react-sdk/js-sdk whatsoever.

@robintown it does not hang up the call Hanging up the call might be appropriate, but I guess we'll get product/design to run through the problem and we can decide how to proceed
