📋 Summary

Related Issue: N/A (minor fix)

🎯 What

In the checkout session, i added the cursor-pointer on the close button.

🤔 Why

The element was already clickable, but the cursor did not reflect that,
making it appear broken or non-interactive.

🔧 How

Added the missing cursor-pointer style to the existing component.
No logic or behavior changes were made.

🧪 Testing

• I have tested these changes locally
• All existing tests pass (uv run task test for backend, pnpm test for frontend)
• I have added new tests for new functionality
• I have run linting and type checking (uv run task lint && uv run task lint_types for backend)

Test Instructions

1. Navigate to the effected page
2. Hover over to the close button
3. Verify the cursor changes to a pointer
