Remove mostly-unsued fetch handler.

This was added as part of the original service worker spike, without much consideration for design goals or correctness, and while it _works_, it doesn't meet any specific needs. We can get most of the same behaviour by letting the browser handle fetches directly.

The main thing we lose is offline rendering of the Pilcrow UI, but that only worked partially and only by accident. We should build that from the ground up.
