Summary

Adds a clientless AWS service emulator fixture (ministack_service / localstack_service) defaulting to MiniStack (ministackorg/ministack:latest) for active, MIT-licensed, tokenless emulation of AWS services, with drop-in compatibility for LocalStack images and health check probes.

Key Changes

AWS Service Emulator (pytest_databases.docker.localstack)

• MiniStack Default: Pinned default image to ministackorg/ministack:latest, providing actively maintained, tokenless offline emulation across AWS services without requiring account tokens or paid subscriptions.
• LocalStack Compatibility: Preserves LocalStackService, localstack_service, and localstack_image fixtures as drop-in aliases with optional LOCALSTACK_AUTH_TOKEN support for commercial image opt-in.
• Container-Native Readiness: Validates service readiness using an in-container HTTP probe supporting both python3 stdlib urllib.request and curl fallbacks across /_ministack/health and /_localstack/health endpoints.
• Worker Isolation: Supports shared container execution with per-worker resource prefixes (database isolation) and per-worker containers (server isolation) via xdist_ministack_isolation_level / xdist_localstack_isolation_level.

Testing, Documentation & CI

• Unit & Integration Coverage: Tests verify clientless module import, MiniStackService and LocalStackService aliases, queue creation, message send/receive/delete round-trips via exec_aws_cli, and pytest-xdist worker isolation.
• Documentation & Selective CI: Updates docs/supported-databases/localstack.rst and registers ministackorg/ministack:latest in .github/ci/provider-groups.json.
