interactive: allow moving horizontally/vertically maximized window
Applies drag resistance unidirectionally for horizontally/vertically maximized windows, allowing them to be dragged without being untiled immediately. When the distance of cursor movement orthogonal to the maximized direction exceeds <resistance><unMaximizeThreshold>. While dragging a horizontally/vertically maximized window, edge/region snapping is disabled to prevent unintentional snapping and overlays. This commit also includes some refactoring to simplify the logic.
