Replace localstack with ministack

[Nahuel990]

Swaps the S3 test container image from localstack/localstack:s3-community-archive to ministackorg/ministack:1.4.16, resolving the existing TODO: Switch the localstack image. ministack is an open-source (MIT) AWS emulator that serves the S3 API on the same port (4566) and works under the existing LocalStackContainer fixture with no other changes.

Disclosure: I maintain ministack.

Verified locally by reproducing this file's Testcontainers usage against ministack — the NetworkAwareLocalStackContainer start-override pattern, with_services('s3'), and get_client('s3'), then create_bucket, put_object/get_object, and list_buckets on test-bucket all pass.

Summary by CodeRabbit
