refactor(ui): move scale property to subclasses and fix resize event handling

Browse Source 
Remove scale from base Widget class and add per-type set_scale/scale methods to Button, Image, and Label. Dispatch separate WindowResizeEvent alongside existing FrameBufferResizeEvent. Correct centering calculations from `+` to `-` in main menu and world UI managers.
