Move frontend logging to `debug` library.

[hobofan]

We have quite a lot of logging in the frontend, which is good, but we also don't have good filter mechanisms for selectively enabling logging. There are some parts for this in frontend/src/utils/debugLogger.ts, but I think it would be good to use an established library for that rather than building something ourselfes.

One commonly used library for doing that in the browser is debug. One example of a library using it is socket.io-client, which uses it like this:

import debugModule from "debug"; // debug()

const debug = debugModule("socket.io-client:url"); // debug()

debug("protocol-less url %s", uri);

It can then be selectively enabled like this in the browser console:

localStorage.debug = "socket.io-client:*";
