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

[Cukurikik]

💡 What: Added aria-label attributes to the icon-only buttons in the Assistant page (Attach file, Send Image to Vision Model, Voice Input, Cancel request, Send message).
🎯 Why: To improve keyboard navigation and screen reader support, as icon-only buttons without text lack context for users relying on assistive technologies.
📸 Before/After: Visuals remain unchanged.
♿ Accessibility: Screen readers will now announce the exact purpose of these buttons.
