Describe the bug

Description

The clipboard copy button in the landing page lacks an accessible label, causing accessibility violations for users relying on screen readers.

Current Behavior

The <Menu.Button> component in ClipboardSelect.tsx has no associated label, making it inaccessible to screen reader users. The button only contains an SVG icon without any text or aria-label.

Expected Behavior

The button should have a proper accessible label so screen reader users can understand its purpose.

Accessibility Impact

• WCAG 2.1 Level A: Fails 4.1.2 Name, Role, Value
• Impact: Screen reader users cannot identify the button's purpose
• Severity: Medium - Core functionality is inaccessible

Proposed Solution

Add aria-label="Copy to clipboard" to the Menu.Button and mark the decorative SVG icon as aria-hidden="true".
