Stacked on #11.

Summary

• management.json holds every bucket and container operation, so operations.json holds object operations only. The 22 existing cases moved and are renamed management/<profile>/<name>, such as management/s3/create-bucket.
• Four new cases cover the calls that build a live test setup:
  • management/s3/put-bucket-versioning turns versioning on.
  • management/s3/get-bucket-versioning reads it back, and get-bucket-versioning-never-enabled reads a bucket that never had it.
  • management/s3-express/create-bucket creates a directory bucket through the regional control endpoint s3express-control, by path, signed with the account credentials and no session.
• All 26 were verified live.

For clients

• A case ID that started operations/ for a bucket or container operation now starts management/.
• New operations: s3.put_bucket_versioning with status, s3.get_bucket_versioning, which reports status, and availability_zone on s3.create_bucket for a directory bucket.
• The s3-express profile of management.json names its control endpoint in control_url.

Test plan

• object-tests validate passes for cases/operations.json (970 cases) and cases/management.json (26 cases).
• cargo test passes.
