- Create INeighborhoodScoreService interface and implementation
- Score districts 0-100 across 6 categories: education, healthcare, transport, shopping, greenery, safety
- Calculate scores from POI data with configurable weights and max counts
- Add GetNeighborhoodScoreQuery handler with lazy calculation
- Add GET /analytics/neighborhoods/:district/score endpoint
- Wire service and handler into AnalyticsModule
