Do signature checking in the background

[jb55]

We should have a work queue to process things in the background, like preloading PFPs, etc. We shouldn't see anything popping in.

This is done for PFPs now but we'll probably need it for processing signatures since that seems to be blocking the thread when scrolling on slower devices

We need to do a bunch of processing in the background when we received a post. I've noticed the parsing content for mentions, etc can be somewhat time consuming as well. so perhaps this call all be done right away in a work queue.
