feat: persist and expose resolvedEndpointUri for execution-level drill-down

Wire resolvedEndpointUri through the full chain:
- V9 migration adds resolved_endpoint_uri column
- IngestionService extracts from ProcessorExecution
- PostgresExecutionStore persists and reads the column
- ProcessorNode includes field in detail API response
- UI schema updated for ProcessorNode and PositionedNode
