use editor-format graphStep directly for step config form

The `graphStep` passed to `WorkflowInvocationStep` is already the full editor-format step loaded via `getWorkflowFull` (style=editor) in `useInvocationGraph`. It already has `config_form` populated with the correct parameter values, as well as `label`, `tool_state`, and `post_job_actions` — so there is no need to call `build_module` at all in the graph view.

`activeStepWithConfig` now returns `graphStep` directly when its `config_form` is present, rendering the form immediately with no network roundtrip and showing the actual values set in the workflow. The `build_module` fetch is kept as a fallback for non-graph contexts where `graphStep` is absent or incomplete, using `tool_state` (the proper editor-format) instead of the previously used `tool_inputs`.
