Add start/stop methods to SetpointManager and fix main application configuration

- Added async start() and stop() methods to SetpointManager for main application compatibility
- Fixed database pool configuration to use correct settings parameter names
- Added missing settings: opcua_host, modbus_host, modbus_unit_id, rest_api_host
- Updated protocol server initializations to pass required dependencies
- Fixed OptimizationPlanManager method calls to use correct names (start_monitoring/stop_monitoring)
- Verified main application starts and stops gracefully
- All 133 tests continue to pass
