FileUpload: add cors proxy to uploads for web (#754)

this allows uploads to Nest and E-Z to work on equibop/web,
and the proxy is hosted on workers so it should have good
uptime and latency.

i can send the code if you or creations want to host it
instead if that's preferable, since i know relying on too
many external apis is yucky
