Refactor imports and add auth clearAll

- Remove unused SetStateAction import in SideBar - Add clearAll to
authStore to wipe state, localStorage, and reset notes - Expose
useAuthStore on window for debugging - Update notesStore.updateFolder to
return FolderTreeNode and fix recursion by using the correct child
variable
