refactor(docker-compose and db init): rewrote docker-compose to work purely with env variables

It is possible to rename the default db in a postgres container instance via an env variable. This
renders the initdb script useless. The only shortcoming is that the app now uses the db root user
which is not ideal but its fine for a dev environment.
