chore: set up proper postgres config for dev and CI

[superlinkx]

Description

Sets up a better default postgres config for local development. This will eventually get tuned into a default for running bhce graphs on Postgres, but for now it's limited to dev and CI uses.

Motivation and Context

This PR addresses: BED-5510

Allows running much larger graphs with reasonable analysis times

How Has This Been Tested?

Ran all updated scripts/docker compose files to ensure things are running properly
Tested with a larger testing dataset to validate that analysis times match up with expectations

Types of changes

• Chore (a change that does not modify the application functionality)
