fix: unify NumberBox drag behavior to prevent value jumps in limited mode 

The limited drag mode used absolute mouse position to compute the
  value (min + xPercent * range), causing an immediate jump away from
  the property's current value at drag start. Unify both modes to use
  the relative offset formula (number + offset * step), with the
  limited mode only adding min/max clamping on top. Also removes the
  cursor-constraining logic that was specific to the old absolute mode.
