Split Hash Collisions into own tab, add hop distances to route patterns

Browse Source 
- Hash Stats tab: general hash size distribution, top hops, timeline
- Hash Collisions tab: 16x16 usage matrix + collision risk analysis
- Route Patterns detail: inter-hop distances with color coding
  (green <50km, amber 50-200km, red >200km) and total path distance
