[YNDX-00518 / Yandex] local_temperature_calibration adjustment limits

[dmatyas]

What happened?

If I try to set a value less than -2.5 or greater than +2.5, an error appears in the log:
[01.01.2026, 23:20:19] z2m: Publish 'set' 'local_temperature_calibration' to 'Радиатор спальня 2' failed: 'Error: localTemperatureCalibration requires min of -25'
Local temperature is not adjusted in this case.

What did you expect to happen?

According to the documentation, the temperature control range should be -12.8 °C ...+12.8 °C

How to reproduce it (minimal and precise)

Just try to set Local temperature calibration to -2.6 °C or lower via the web interface.
