Implement Restricted Close Mode for UpWindowAngularComponent

[lucasferreiralimax]

We need to enhance the UpWindowAngularComponent to support a "restricted mode" where the modal can only be closed using the "Cancel" or "Confirm" buttons. In this mode, the close button (×) should be hidden, and clicking on the overlay should not close the modal.

Acceptance Criteria:

1. Restrict Mode Input:

   • Add an input property restrictMode: boolean to the UpWindowAngularComponent.
   • When restrictMode is set to true, the following changes should apply:
     • The close button (×) should not be displayed in the modal header.
     • Clicking on the overlay should not close the modal.

2. Behavior:

   • If restrictMode is false:
     • The close button should be visible, and clicking it should close the modal.
     • Clicking on the overlay should close the modal as usual.
   • If restrictMode is true:
     • The modal should only be closed by clicking the "Cancel" or "Confirm" buttons.

Implementation Notes:

• Update the component template to conditionally render the close button based on the value of restrictMode.
• Modify the click event on the overlay to check the value of restrictMode.

Example Usage:

<up-window-angular
  [isOpen]="isModalOpen"
  [restrictMode]="true"  <!-- Activates restricted mode -->
  title="Modal Title"
  subtitle="Modal Subtitle"
  (confirm)="onConfirm()"
  (cancel)="onCancel()"
>
  Modal Content
</up-window-angular>
