        TODO: Refactor action buttons to use a declarative config system.

        Instead of hardcoding button visibility logic in the template, define an array of
        action button configs with properties like:
        - icon, label, action, tooltip
        - visibleStates: JobState[] (which job states show this button)
        - alwaysVisible: boolean (show without hover)
        - destructive: boolean (use destructive styling)

        Then render buttons in two groups:
        1. Always-visible buttons (outside Transition)
        2. Hover-only buttons (inside Transition)

        This would eliminate the current duplication where the cancel button exists
        both outside (for running) and inside (for pending) the Transition.
