Diffusion - return 404 errors for bad URIs

Summary: Fixes T5646. Makes diffusion a much better user experience. Users now see a 404 exception page when they have a bad URI. Previously, they saw a developer-facing raw exception. Test Plan: played around in diffusion a bunch. most of these changes were fairly mechanical at the end of the day.
