Fix AS detail view to show unique prefixes

Browse Source 
- Update GetASDetails query to GROUP BY prefix instead of using DISTINCT
- Use MAX(last_updated) to get the most recent update time for each prefix
- This prevents duplicate prefixes from appearing when announced by multiple peers
- Maintains the same prefix count and ordering
