[Fix #1507] Loading HttpRequestDecorator from WorkflowAdditionaObject

Fix #1507

[Copilot]

Pull request overview

This PR addresses #1507 by enabling HttpRequestDecorator instances to be provided at the application level (via WorkflowApplication “additional objects”), rather than only via ServiceLoader, allowing decorators to hold application-scoped state.

Changes:

• Load and sort HttpRequestDecorator instances in HttpExecutorBuilder, combining application-provided decorators with ServiceLoader decorators, and pass them into HttpExecutor.
• Extend WorkflowApplication.Builder with a withAdditionalObject(String, Supplier<T>) overload and add a corresponding additionalObject(String) accessor.
• Add unit tests covering WorkflowAdditionalObject and supplier-based additional objects.
