add socket-events import to entry point

socket-events aren't ever imported, if we don't do that however
webpack never actually sees any code that leads to it and skips
bundling it.

So for now, do an import that has the side effect of registering
all the events until we have a proper registration in place that's
a bit more sane to call

client/js/vue.ts
