User agreement

Description
With a user agreement, an appropriately authorized person confirms that the
currently displayed SI actual position of an axis corresponds to the actual position
at the machine.
This can be checked by traversing the axis to a known position (e.g. a visual mark)
or the axis is adjusted/calibrated and the SI actual position is therefore compared
in the "user agreement" screen.
An axis/spindle with integrated safety functions can have the following status:
User agreement = yes, or
User agreement = no
