🎨 Palette: Add tooltip explaining disabled button state to Trust Ops queue

[mapleleaflatte03]

💡 What

Added title="Select items first" tooltips to the disabled bulk action buttons (approve, stale, revoke, unresolved) in the Trust Ops Queue. The JavaScript logic was updated to dynamically remove the tooltip when a queue item is selected and the buttons are enabled.

🎯 Why

Disabled buttons can be confusing without context. While it may seem obvious to an experienced operator that they need to select a queue item first, new users or users with cognitive disabilities benefit from explicit feedback on why an action is unavailable.

📸 Before/After

Before: The buttons were disabled with a lowered opacity, but provided no hover feedback explaining why.
After: Hovering over the disabled buttons now displays a native browser tooltip reading "Select items first".

♿ Accessibility

Improves context and clarity for cognitive accessibility by explicitly stating the requirement to unlock the disabled controls, using native HTML attributes without introducing custom CSS.
