Fix server freeze from unresponsive logo/image hosts

requests.get() calls had no timeout and ran directly on the aiohttp
event loop, so a single dead logo host would hang for minutes and
block every other request. Add timeouts and move logo downloads in
get_logo to a thread executor so a slow/dead host no longer stalls
the whole server.
