Implement AS and prefix detail pages
- Implement handleASDetail() and handlePrefixDetail() HTML handlers - Create AS detail HTML template with prefix listings - Create prefix detail HTML template with route information - Add timeSince template function for human-readable durations - Update templates.go to include new templates - Server-side rendered pages as requested (no client-side API calls)
