ENP Docker overhaul

[cris-oddball]

User Story - Business Need

Whilst performing other work, there appear to be problems with the way the container is Dockerized. This ticket aims to overhaul that container and documentation.

• Ticket is understood, and QA has been contacted (if the ticket has a QA label).

User Story(ies)

As a VA ENP dev
I want a consistent, repeatable Docker container
So that development is simplified

Additional Info and Resources

Issue 1: the Poetry version is pinned down to 1.8.3 when we upgraded to 1.8.4 within the last three months.
Issue 2: Kyle had issues running the existing container (see him for details).
Issue 3: bash is not in the Docker build but the script runs bash

Acceptance Criteria

• the ENP docker container is overhauled for consistency
• Docker locks it to Poetry 1.8.5
• if a bash script is to be run, then bash must be in the $PATH, or clear documentation is included for how the script runs
• Issues discovered from the GHA Deploy ticket are addressed (such as cert/port/etc.)
• Documentation is updated
• This work is added to the sprint review slide deck (key win bullet point and demo slide)

QA Considerations

• Validate all work performed.

Potential Dependencies

This work is dependent on the ability to deploy images.
The task needs to be running and the load balancer needs to point to it.

Need to re-evaluate if necessary.
Discussed with the dev that recently overhauled the container. We want to keep this until after the container has been deployed because we expect some wrinkles that will need to be ironed out.
