Dockerize all services (for Kubernetes)

[digisomni]

We should split out pg_web from the postgres image, we should also bundle our bun + services into their own docker containers, thus all services can be provisioned and run via Kubernetes.

The actual Bun provisioning scripts and CLIs should of course remain local and be used to provision as we do now.

So it'll be a challenge of sorting upstream -> downstream configurations and how to make everyone work with eachother via environment variables configuring who should work with who.
