🎨 Palette UX Improvement: Accessible Downloads Queue Drawer

💡 What:

Enhanced QueueDrawer with proper dialog semantics, Escape key dismissal, and keyboard focus restoration:

• Integrated QueueDrawer with overlayStack (pushOverlay / popOverlay) to close when the Escape key is pressed if it's the topmost overlay.
• Captured previously focused element on drawer open and restored focus to it on drawer close.
• Added role="dialog", aria-modal={isOpen}, and aria-label="Downloads".
• Added aria-hidden={!isOpen} and inert={!isOpen ? true : undefined} to ensure assistive tech and keyboard navigation skip offscreen drawer content when closed.

🎯 Why:

Previously, the QueueDrawer stayed mounted off-screen when closed, allowing keyboard navigation to tab into hidden interactive elements. Additionally, pressing Escape did not dismiss the drawer, and closing it did not return focus to the triggering button.

♿ Accessibility:

• Full screen reader dialog announcement and labeling (role="dialog", aria-label="Downloads").
• Keyboard accessibility: Escape dismisses the drawer, focus is smoothly returned to the trigger, and closed off-screen states are inert.
