Refactor the monitoring daemon integration tests to use local Docker-managed dependencies instead of direct AWS dependencies. First, create a docker-compose.yml file with two services: a PostgreSQL container with test credentials exposed on port 5432, and a LocalStack S3 container exposed on port 4566. Next, modify the test file to remove reliance on external AWS credentials and replace them with fixtures that configure a LocalStack S3 mock. The fixtures should include session-scoped setup for hostnames, PostgreSQL connections, and AWS environment variables with hardcoded test credentials (e.g., fake access keys). Ensure the S3 fixture initializes a test bucket. Move the AWS environment fixture to align with other fixtures and update the test logic to use the new LocalStack endpoint URL, handling both local and Buildkite environments. Keep the core test cases (like monitoring run attempts) intact but adapt them to use the new Docker-based dependencies.
