🎨 Palette: Add ARIA labels and hide visual text for icon-only buttons in ConversationsSidebar

[Dexploarer]

💡 What

Added missing aria-label to the "Delete conversation" icon-only button and wrapped the visual text icons (× and ×) inside <span aria-hidden="true"> in the ConversationsSidebar component.

🎯 Why

Screen readers will reliably read the aria-label attribute on the button, and hiding the visual text ensures that it isn't awkwardly announced as "times" or "multiplication sign" along with the intended action text.

📸 Before/After

Before:

<button ... title="Delete conversation">×</button>
<button ... aria-label="Close chats panel">&times;</button>

After:

<button ... title="Delete conversation" aria-label="Delete conversation"><span aria-hidden="true">×</span></button>
<button ... aria-label="Close chats panel"><span aria-hidden="true">&times;</span></button>

♿ Accessibility

This improves screen reader compatibility when interacting with the Conversation sidebar, preventing confusing announcements for icon-only buttons.

Consider using optional chaining (onClick={onClose} → onClick={onClose ?? undefined}) or a defensive check to ensure that if onClose is not provided, no error is thrown. While the current usage is safe if the parent always provides the prop when mobile is true, this makes the component more robust to future changes.

Code Review

This pull request significantly improves the accessibility of icon-only buttons in the ConversationsSidebar component. By correctly adding aria-label attributes and wrapping visual icons with aria-hidden="true", screen readers will now provide a much clearer and more accurate experience for users. This directly addresses the stated goal of preventing confusing announcements and enhancing screen reader compatibility.

[gemini-code-assist]

The addition of aria-label on the button and wrapping the visual icon with <span aria-hidden="true"> is an excellent accessibility improvement. To further enhance maintainability and promote consistency across the application, especially if this pattern is used in multiple places, consider abstracting this into a dedicated IconButton component. This component could encapsulate the accessibility best practices, ensuring they are consistently applied wherever an icon-only button is used.
