🎯 The Problem (Super Quick)

What's wrong?
When you enable "Scan to Boxes" and scan a product with defect code 000, a modal popup appears. But the "Create New Box" button is hidden (display: none) in the form instead of being visible in the modal.

What's the result?
Users don't see they can create boxes → think feature is broken → feature unusable

What's the fix?
Move button from form into modal (3 code changes in 1 file)

How long?
15 minutes total (5 min read + 5 min code + 5 min test)
