Hide the Workflow Visualizer button on Job Slices

[cigamit]

Job slices create an "adhoc" Workflow, so there is no actual Workflow behind the scene. The visualizer errors when clicking it on these job slices as there is no actual Workflow.

Pull request overview

This PR updates the Workflow Output toolbar in the AWX UI to avoid showing (and attempting to navigate with) the Workflow Visualizer action for job slices, which do not have a real backing workflow template and currently error when the visualizer is invoked.

Changes:

• Derive the visualizer target template ID from job.summary_fields.workflow_job_template and only navigate when it exists.
• Conditionally render the “Edit workflow” (visualizer) button only when a workflow template ID is present.
• Extend the toolbar test coverage to assert the visualizer button is hidden when workflow_job_template is null.
