Make GPIO read output match write format

[be-student]

Fixes #437

Summary

• show GPIO read masks and masked values in hexadecimal
• match the existing GPIO write output format
• cover direct, masked, and protobuf-default zero responses

Validation

• pytest -q -m unit — 421 passed
• mypy meshtastic/ — 80 files clean
• pylint meshtastic examples/ — 10.00/10

AI-assisted; reviewed and validated by me.

Summary by CodeRabbit

• Bug Fixes

  • GPIO read responses now use consistent hexadecimal formatting for masks and values, matching the notation used when writing GPIOs.
  • Masked GPIO values are reported accurately, including cases where GPIO data is missing.

• Tests

  • Added coverage for masked values, missing GPIO data, hexadecimal output, and response handling.

📝 Walkthrough

Walkthrough

The GPIO receive callback now reports the mask and masked value in hexadecimal notation. The related parameterized test signature now includes type hints.

Changes

GPIO reply formatting

Layer / File(s)	Summary
Format and validate GPIO replies meshtastic/remote_hardware.py, meshtastic/tests/test_remote_hardware.py	onGPIOreceive converts the mask once, applies it to the GPIO value, and prints hexadecimal mask and value fields. The parameterized test signature includes explicit type annotations.
