Run all BCIERS apps in CI to test inter app functionality

[marcellmueller]

Describe the task

Currently we have set up e2e testing in CI to test each app which runs the Dashboard app and the app being tested (eg Reporting, Administration, Registration etc). Now that the difficult work of getting the apps to communicate properly in CI has been done we should create a docker-compose file and create a Dashboard job that runs all apps and supports testing inter-app functionality for example a user going from Registration to Administration.

The work in creating a docker-compose file/action that will run the entire app can be reused for #2195

Acceptance Criteria

• Create docker-compose file that runs all apps simultaneously (rather than just Dashboard and one app like the current file)
• Create a run-bciers-apps action that can be reused that runs this compose file
• Create a GitHub workflow that runs this e2e test - currently we don't have a Dashboard one so it makes sense to do these tests in dashboard-e2e project. Or maybe create bciers-e2e?
• Write very basic tests that show Happo screenshots of all apps working correctly
