fix: news feature security, accessibility, performance improvements
- DOMPurify strict allowlist with sandbox on iframes - safeColor() CSS injection prevention for category_color - URL validation (http/https) for images and links - encodeURIComponent for slug in API calls - Keyboard navigation on news cards (Enter/Space) - aria-label, aria-pressed, type=button on all buttons - 44px touch targets on remaining buttons - memo() wrappers + stable callbacks (fewer re-renders) - Canvas draw call batching (~75% reduction) - TipTap extensions useMemo deps fix ([t] -> []) - Featured image loading=eager fetchPriority=high (LCP) - Unsafe Number(id) NaN guard
