dwindle: fix windows being created at incorrect position when cursor is over reserved area (#4520)

* fix: smart_split not working correctly when creating a window with cursor over reserved area

* use getClosestNodeOnWorkspace instead of getFirstNodeOnWorkspace when hovering over reserved area

* optimize `getClosestNodeOnWorkspace`

* remove unused methods
