Add a toggle for the custom web logo

The feature could only be turned off by clearing the uploaded image, and
its fallback pointed at /favicon.ico, which current ComfyUI does not
serve at all, so disabling it left a dead icon rather than the original.

Remember whatever favicon ComfyUI has at setup, before any job has run,
and restore that when the toggle is off. If there is nothing to restore,
leave the favicon alone rather than pointing it somewhere broken.
