Remove Loader startup/shutdown as it's not needed

[tofu-rocketry]

We don't need to startup and shutdown the Loader as we're not running it as a Daemon. We're invoking its load_msg method and passing it a message to load directly.

I thought about this when I implemented it the first time. But I couldn't remember what I had decided before my VM died, and then when I was rushing to rewrite the code on the new VM before I went on leave, I thought it was safer to leave in.

Fair enough. When working through a fresh deployment I realised it would need a lot more configuration to work if we're running the Loader as a Daemon.
