feat: add docker support and docker-compose quickstart

Add support for production container builds using the provided `Dockerfile` and `build.sh` script. This can later be used with actions to automatically publish to the provided docker registry.

Additionally, support an accelerated developer quickstart using `docker-compose`. Developers can now run the `dx` npm command to quickly spin up a database and mail server.
