[feat] Improve queue job item UX based on design feedback

- Running jobs now show cancel button at all times (always visible)
- Cancel/delete buttons use destructive red styling by default
- Changed pending job icon from clock to loader-circle with spin animation
- Fixed icon buttons to be square (size-6) instead of rectangular
- Added TODO comment for future declarative button config system

+        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.
