enh(ui): use a 3 columns system for SParameters

Description

These changes modify SParameters layout to use a 3 columns system instead of the current 6 columns system, in order to improve usability of the second and third spinboxes. In addition, the labels of the parameters now can wrap if they are too wide, and a bug where the second and third spinboxes wouldn't be disabled if the depend is disabled is fixed as well.
