Feat: Fall back to Bing when Brave refuses, and serve donate.webp when Bing blocks too

Browse Source 
Brave errors (e.g. its spending limit being hit) now fall back to Bing
like empty results do, with the error in a Brave Unavailable alert. If
Bing fails too (HTTP error or a page without results, which for Bing
means it's blocking us), a new papercraft donate.webp is served instead
of an AI image, and nothing is cached so the query works once either
search is back.
