v2.10.1 bugfixes

[HAEdwin]

No new features this time, but a handful of bug fixes that will hopefully improve how the integration works.

• More specific error messages
  All error messages now clearly indicate which operation (ECU, inverter, signal, meter, or socket) was being performed when the error occurred.
• Socket resource management was improved
  The socket resource cleanup is now handled correctly by closing only the local socket that failed to connect. All socket errors now properly trigger socket cleanup to prevent resource leaks.
• Removed overly strict data length validation that was causing false socket connection errors
  Prevents misleading "failed to claim socket" errors when ECU sends legitimate short responses and improves compatibility with ECU firmware variations and different inverter configurations. The integration now properly handles cases where inverter details are temporarily unavailable.
