Allow desktop app to connect to selfhosted servers (#4902)

# Description of Changes Changes the desktop app to allow connections to self-hosted servers on first startup. This was quite involved and hit loads of CORS issues all through the stack, but I think it's working now. This also changes the bundled backend to spawn on an OS-decided port rather than always spawning on `8080`, which means that the user can have other things running on port `8080` now and the app will still work fine. There were quite a few places that needed to be updated to decouple the app from explicitly using `8080` and I was originally going to split those changes out into another PR (#4939), but I couldn't get it working independently in the time I had, so the diff here is just going to be complex and contian two distinct changes - sorry 🙁
