That PR I keep mentioning.

• Docker builds and runs with local storage (and the container is auto-built on push to the main branch, and pushed to ghcr.io)
• Config's all in a Pydantic model now.
• loader.py can do multiple loads in a row so it's not starting up multiple times
• SO much chasing types through flows
• moved testing to use pytest (which meant renaming vigil-server.py)
• ... probably other stuff I've forgotten

If there's anything you'd rather be done a particular way, don't hesitate, we all have our preferred ways of doing things 😄

@yaleman Would you be able to break this PR down into separate PRs that are more feature specific? This is really hard to review and merge as one PR since I have to take all or nothing from this branch
