Add resize functionality and improve dialog controls

Browse Source 
This commit introduces the ability to resize dialogs by adding `CanResize` properties to dialog options and control classes. It also refines dialog controls' behavior and layout, ensuring consistent resizing capabilities across different dialog types. Additionally, it enhances the overlay feedback element's positioning logic and updates the resizer's appearance and visibility handling.
