We have implemented a new fullscreen mode for the modal component (UpWindowAngularComponent). The modal should now be able to expand to fill the entire screen instead of opening in the center.

Current Behavior

Currently, the modal opens in the center of the screen with a defined size.

Expected Behavior

When the fullscreen mode is activated:

• The modal should expand to cover the entire viewport.
• The content inside the modal should be properly adjusted to fit the fullscreen view.

Implementation Details

• A new @Input() fullScreen property is introduced to manage the fullscreen state.

Steps to Reproduce

1. Open the modal.
2. Trigger the fullscreen mode.
3. Observe that the modal expands to fill the screen.
