PR #482 Review: Add empty states for most pages

The empty state system is well-structured with good component composition. A couple of things worth addressing:

---

🔵 Minor — Security: window.open missing noopener/noreferrer

In EmptyState.tsx, both handleLearnMoreClick and handleDocsClick open URLs in a new tab without setting the security options:

// EmptyState.tsx ~line 192, 207
window.open(learnMoreLink, '_blank')
window.open(docs[selectedType], '_blank')

Without noopener,noreferrer, the opened page gets a reference to window.opener, enabling tab-napping. Fix:

window.open(learnMoreLink, '_blank', 'noopener,noreferrer')
window.open(docs[selectedType], '_blank', 'noopener,noreferrer')

🔵 Minor — UI: NoLiveConfig renders buttons before description

NoLiveConfig renders in a different order than all other empty states:

// NoLiveConfig.tsx — current order
<EmptyStateTitle>...</EmptyStateTitle>
<EmptyStateButtons ... />   // ← buttons appear before description
<EmptyStateContent>...</EmptyStateContent>

Every other empty state (via EmptyState) follows: icon → title → content → buttons. This means in the Live Config page, "Learn more" and "Go to docs" appear above the explanatory text, which reads strangely. Swapping EmptyStateButtons and EmptyStateContent would match the established pattern.
