Fix splitter drag acceleration by removing stretch factors

Browse Source 
setStretchFactor on QSplitter interferes with manual handle dragging —
Qt applies stretch redistribution after each mouse move, compounding
the delta and creating an accelerating effect. Replaced with size
policies (Expanding on right panel) which achieve the same window-
resize behavior without fighting the splitter drag.
