openhands f55a4ccf68 Fix Modbus performance registers and add protocol architecture documentation 
- Extended Modbus server input register range from 300 to 400 registers
- Fixed IllegalAddress errors for performance registers (400-499)
- Added timeout protection for Modbus operations in dashboard API
- Added protocol architecture diagram to documentation
- Confirmed both OPC UA and Modbus servers are running correctly
- Protocol clients now successfully read real data with 0% error rate

Test Results:
- OPC UA: 15/15 signals active, 0% error rate
- Modbus: 18/18 signals active, 0% error rate
- REST: 3/3 signals active, 0% error rate
