feat: Performance optimizations and preflight improvements

Browse Source 
- Add missing /api/analytics/national/summary endpoint
- Optimize dashboard activity queries (subquery vs JOIN+GROUP BY)
- Add PreflightSummary component to Workers page with gold qualified badge
- Add preflight retry logic - workers retry every 30s until qualified
- Run stale task cleanup on ALL workers (not just worker-0)
- Add preflight fields to worker-registry API (ip, fingerprint, is_qualified)

Database indexes added:
- idx_store_products_created_at (for recent products)
- idx_dispensaries_last_crawl_at (for recent scrapes)
