[Bug] Recalibration hall effect overwrite manual calibration #469

Describe the Bug

Hello, I have a Keychron K10 HE and I've been noticing some errors when checking the switch millimeters, changing the actuation point, or using rapid triggers.

After manual calibration, key travel reports correctly from 0 mm to 4 mm.
However, after some usage and/or after reboot, the reported full travel changes (for example from 4.0 mm to 1.9 mm), suggesting calibration values are being modified dynamically.

I traced the behavior to the dynamic auto calibration logic inside:

auto_caliration_check(row, col, value);

especially:

calib_values[row][col].zero_travel = p->value.zero_travel;
calib_values[row][col].full_travel = p->value.full_travel + BOTTOM_JITTER;

followed by:

save_calibration_value(row, col);

It appears that manually calibrated values may be overwritten during normal usage and persisted to EEPROM automatically.

This is especially noticeable with Rapid Trigger / gaming usage where consistent travel distance is critical.

It may be useful to provide an option to disable dynamic auto calibration or EEPROM auto-save after manual calibration.

Thanks.
