🎨 Palette: Improve hit targets and accessibility for list rows

[acebytes]

💡 What
Wrapped the contents of CategoryRow and NodeModulesRow entirely inside a Button with .contentShape(Rectangle()) rather than only making the checkbox an interactive element. Applied .accessibilityElement(children: .combine) to group the text content.

🎯 Why
Previously, clicking anywhere in the row except exactly on the tiny checkbox did nothing, leading to a frustrating experience when trying to quickly select multiple items. Additionally, VoiceOver would read every single text element (name, path, size, badge) as a separate element, fragmenting the context.

📸 Before/After
Before: Only the 24x24 checkbox icon is clickable. VoiceOver reads elements individually.
After: The entire row width/height is clickable. VoiceOver reads the row as a single cohesive element.

♿ Accessibility

• Expanded minimum tap target size to far exceed guidelines for list items.
• Combined VoiceOver elements into a single logical group per row using .accessibilityElement(children: .combine).
