💡 What: Replaced raw <button> tags with the IconButton component for icon-only buttons.
🎯 Why: The IconButton component enforces aria-label which improves accessibility and maintains consistency across the app interface.
📸 Before/After: Visuals will have identical structure but slightly cleaner focus and hover states consistent with other icon buttons.
♿ Accessibility: Ensures that all icon-only actions are screen-reader accessible with an explicit aria-label.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!
