🎨 Palette: Add tooltips to disabled bulk action buttons

[mapleleaflatte03]

💡 What: Added tooltip wrappers with title and dynamic tabindex to the disabled bulk action buttons on the Trust Ops Queue operator surface.

🎯 Why: To let users know why the buttons are disabled ("Select items to apply action") rather than leaving them un-clickable without context.

📸 Before/After:

• Before: Buttons were completely non-interactive and provided no feedback when hovered or navigated to via keyboard.
• After: Buttons are wrapped in an inline-flex span. When disabled, the span receives tabindex="0" and a title, so the reason for the disabled state is visible on hover or focus. When enabled, these attributes are stripped to prevent double-tab-stops.

♿ Accessibility: Ensures that keyboard users and screen readers can interact with the disabled element wrapper and understand the state of the action, which native disabled <button> elements drop in most modern browsers.
