App/block clock does not reflect network disconnection

[yashrajd]

The application & the block clock do not display an error state when network connection is lost.

Something like this? Not sure if it is implemented.

Actual behavior
This one is on the build from #311

This one is from a older build.

I've observed this more than once.

Repro: Turn off wifi when the app is running. I think it also occurred when the app is launched and the wifi is off.

Running macOS 12.5.6.

Not sure about the technical side of this, but the design is documented here and in Figma (the "no wi-fi" state).

This should also reflect on the peers page.

There are platform specific API's available on essentially all the platforms we support, so this can be done without needing to ping a server. Do we still want to have a specific state for when the device is simply not connected to the internet? I'm in favor of that

Yessir, please.
