Make it able to run in production

- Remove the build Dockerfile, it's not useful on cheap VMs because you can't really build anything on them
- Update the serving address to be 0.0.0.0 so that it's actually exposed externally (127.0.0.1 isn't)
- Also update the port to be 3030 for no reason at all
- Add a Cross.toml config file for cross-compilation since my machine isn't exactly Linux that the resulting binary needs to run on
