ScopedObject must implement both ExtensionContext.Store.CloseableResource
and AutoCloseable to ensure proper cleanup across all JUnit 5.x versions.

JUnit 5.9.x and earlier only recognize CloseableResource for automatic
cleanup. Without it, ScopedObject.close() is never called, causing
resources (Vertx instances, HTTP servers) to leak between test iterations.

JUnit 5.11+ added AutoCloseable support, but we need both interfaces
for backward compatibility with users on older JUnit versions.
