Move live controller code into service, create tests for it

[randomouscrap98]

Just like the file controller, I don't want all this code in the controllers that isn't tested, or testable if I decide not to test it now but require tests later when it inevitably breaks.

At the very least, even if you don't write tests for it, pull the code out and make it testable. Then, anytime in the future there's a bug, write a test for it. Bad test procedure but at least the code will be testable.
