First-time setup and dev docker compose config overhaul

[clpetersonucf]

The goal of this PR is to make the first-time setup process more robust while offering a setup variation for non-developers, to better facilitate an on-ramp for a production environment.

run_first script split

The previous docker/run_first.sh script has been split into two variations:

• run_first_for_dev.sh, more or less in parity with the existing run_first.sh script
• run_first_for_nondev.sh, which provides for a-la-carte configuration options to enable a leaner, faster setup.

Docker compose override changes

The default docker-compose.override.yml file is no longer included by default and is untracked. Dev-specific compose configurations that previously lived in docker-compose.yml now live in a new docker-compose.development.yml. The docker-compose.override.yml file is dynamically authored by either of the two run_first script variants during first-time setup.

Development env variable changes

The previous docker-compose.yml file included explicit references to a variety of environment variable configurations that made it difficult to override. These values have been reduced to dev-specific values that are themselves generated from the docker/.env file. The docker/.env file has been expanded with dev environment variables that can be overridden in docker/.env.local as desired.

nginx configuration changes

There is now a third nginx config: nginx-nondev.conf, which is used in non-dev setups. This configuration bridges the gap between pure dev nginx configs and the production nginx config to allow both previous options to remain unchanged.
