🎨 Palette: [Add ARIA labels to icon-only buttons]

[secrooq]

💡 What:
Added aria-label attributes to the icon-only buttons (Refresh, Close Share Dialog, and Copy Share Link) within the VaultDashboard.tsx component. The copy button specifically uses a dynamic aria-label that changes based on its toggled state (e.g., whether the link has been copied or not).

🎯 Why:
Icon-only buttons present a major accessibility challenge for users navigating with screen readers, as they offer no visible text indicating their purpose. By explicitly defining aria-label attributes, screen readers can now accurately announce the function of these interactive elements. Dynamic labels further enhance the experience by informing the user of successful state changes (like copying a link).

📸 Before/After:
N/A (Visual UI remains unchanged; improvements are within the DOM for screen readers.)

♿ Accessibility:

• Actionable Feedback: Added aria-label="Refresh index" to the reload index button.
• Actionable Feedback: Added aria-label="Close share dialog" to the file share modal.
• Dynamic State Announcement: Upgraded the file share copy button to toggle its aria-label between "Copy share link" and "Link copied" based on user interaction, allowing screen readers to communicate successful clipboard actions.
• Documented the critical learning of dynamic toggle ARIA labels inside the .jules/palette.md journal.
