Add CanResize property to drawers and dialogs with corresponding UI controls

This commit introduces a new `CanResize` property to `DrawerOptions`, `OverlayDialogOptions`, and their respective controls. It also adds UI resizing functionality through the `DialogResizer` control, with styles adjusted to support different drawer positions. Code formatting and organization have been improved for readability across modified files.
