🎨 Palette: Replace anchor tags with semantic buttons & add input ARIA labels

[sheepdestroyer]

💡 What:
Replaced the <a href="#"> used for clearing annotations with a semantic <button type="button"> styled as a link, and added an aria-label to the review note input.

🎯 Why:
Using <a href="#"> for JavaScript actions causes unintended page jumps to the top and is semantically incorrect for non-navigational actions. The input field was missing an accessible label for screen readers.

📸 Before/After:
Before: The "clear" action used an anchor tag (<a href="#">), and the note input relied purely on visual placeholders.
After: The "clear" action uses a <button> tag maintaining the exact visual look, and the input has aria-label="Review note".

♿ Accessibility:

• Improved keyboard and screen reader semantics by using a native button instead of a dummy link.
• Provided a descriptive aria-label for the text input, satisfying WCAG criteria for labeled controls.
