Fix #25581: No pressure sensitivity in sculpt mode

Tablet mode (stylus/eraser) wasn't properly set when pen was already hovering 
over
tablet surface when opening blender (i.e. in cases when blender was opened using
stylus tap).

Issue resolved by setting tablet mode when handling tablet's motion event too.
