ATM Simulator - View: User Interface (UI)

The View class represents the user interface of the ATM system. It is responsible for constructing and displaying all JavaFX UI components including the numpad, menus, transaction history, account details, and settings screens. It accepts user input via button clicks and forwards these actions to the Controller. The display is updated by the UIModel through the update() method.
