🎨 Palette: [UX improvement] Replace interactive anchor with semantic button

[sheepdestroyer]

💡 What: Replaced the interactive <a href="#"> for clearing annotations with a semantic <button type="button">.
🎯 Why: Clicking <a href="#"> tags forces an unintended scroll to the top of the page, disrupting the user experience. Using a semantically correct button prevents this page jump.
📸 Before/After: Visual appearance remains the same.
♿ Accessibility: Improved semantic markup and keyboard navigation.

**issue (testing):** The existing end-to-end test still searches for `.human-review a`, but this change removes the only anchor and renders a button instead, so `test_visualizer_clear_annotation` fails at its visibility assertion before exercising the clear action.
**Triggers:** When the visualizer end-to-end test suite runs.
**Suggested fix:** Update the test locator to target the new button, such as `.human-review button[aria-label="Clear review"]`.
