Updated move action to use move characteristic instead of height monitoring

[sroebert]

When moving the desk to a new position, now the move characteristic is used, instead of moving up/down and monitoring the height changes. This results in a consistent height for the desk and making sure the desk always stops at the exact same position, compared to when using height monitoring.

This matches the logic used in: https://github.com/rhyst/linak-controller

I tested it with my own desk and it works perfectly.
