🎨 Palette: Make list rows fully clickable with VoiceOver support

[acebytes]

• 💡 What: Wrapped CategoryRow and NodeModulesRow in full-width buttons instead of just the checkbox.
• 🎯 Why: Users expect to be able to click anywhere on a list row to select it, rather than carefully targeting a small checkbox.
• 📸 Before/After: Before: Only small checkbox was clickable. After: Entire row is clickable.
• ♿ Accessibility: Grouped row content using .accessibilityElement(children: .combine) and added .accessibilityAddTraits(.isSelected) dynamically so VoiceOver users hear the full context (name, size, risk) and its selection state as a single interactive element.
