🎨 Palette: Wide hit targets & VoiceOver support for list rows

[acebytes]

💡 What

Wrapped the list row contents (CategoryRow and NodeModulesRow) in a plain-styled Button and applied a rectangular content shape. Also combined the inner accessibility elements into a single group and dynamically added the .isSelected trait.

🎯 Why

Previously, only the tiny circular checkbox icon acted as the actionable hit target, forcing users to click with precise accuracy. By expanding the hit target to the entire row (including empty space), interaction becomes much more intuitive and effortless.

📸 Before/After

Before: Only the 20x20 checkbox area registered clicks. VoiceOver read out individual text fragments disjointedly without proper state context.
After: The entire horizontal width of the list item acts as a unified, clickable hit target.

♿ Accessibility

• Added .accessibilityElement(children: .combine) so screen readers announce the row content cohesively rather than stuttering through individual text elements.
• Conditionally applied .accessibilityAddTraits([.isSelected]) when the item is checked, giving VoiceOver users clear state feedback.
