fix: Earthly integration tests use 'earthly/dind' container | NPG-000

[saibatizoku]

Description

CI tests are breaking because Earthly tries to install docker in containers that don't have it, causing unexpected timeouts. As recommended by Earthly Docs, https://docs.earthly.dev/best-practices#use-earthly-dind , this PR updates integration tests to address this problem.

LGTM. I'm assuming this fixed the issue locally?

Holding this PR until the tests are configured to run using Earthly satellites.

This is actually good to go. The tests are running correctly in CI using the Earthly Satellite.
