Ensure no crashes when device is offline

I suspect there are more sources of fatal errors throughout the app than #58 when the device is not connected to the internet.

Any failure to resolve host will cause a fatal error inside a coroutine. So, all of our third-party API requests are likely subject to the same point of failure.

Attempting to wrap our server requests with a safety check for both device and server (check if device is online then check if host can be resolved). Though, we need `context` for this and I'm not sure how this can be injected into `WebScraperManager`, for instance.
