Drop the EOL rustls 0.21 stack from s3-storage aws-sdk-s3's default feature list enables both `rustls` and `default-https-client`. The former resolves to aws-smithy-http-client's `legacy-rustls-ring`, pulling rustls 0.21 and hyper 0.14 into the build alongside the modern stack. rustls 0.21 is end-of-life and carried three open rustls-webpki 0.101.7 advisories. Disable default features and re-enable everything except `rustls`, which leaves the rustls 0.23 path from `default-https-client` as the only TLS stack. This is a shared dependency, so the change closes the same finding in both consumers: the mnw server and multithreaded.
