Replace live_routes database table with in-memory routing table

- Remove live_routes table from SQL schema and all related indexes
- Create new internal/routingtable package with thread-safe RoutingTable
- Implement RouteKey-based indexing with secondary indexes for efficient lookups
- Add RoutingTableHandler to manage in-memory routes separately from database
- Update DatabaseHandler to only handle persistent database operations
- Wire up RoutingTable through fx dependency injection
- Update server to get live route count from routing table instead of database
- Remove LiveRoutes field from database.Stats struct
- Update tests to work with new architecture
