feat: Replace mock data with enhanced mock services

- Enhanced OPC UA server with realistic pump simulation
- Enhanced Modbus server with simulated industrial data
- Updated SCADA API endpoints to query actual protocol servers
- Added realistic signal data based on actual stations and pumps
- Improved SCADA configuration with real device mapping
