Implement Fullscreen Mode for UpWindowAngularComponent

[lucasferreiralimax]

This pull request implements a new fullscreen mode for the UpWindowAngularComponent. The modal can now expand to fill the entire screen instead of opening in the center, enhancing the user experience for viewing content that requires more screen space.

Changes Made

• Introduced a new @Input() property called fullScreen to manage the fullscreen state.
• Modified the component's template and styles to allow the modal to expand and fill the entire viewport when fullScreen is true.
• Adjusted the content layout within the modal to fit the fullscreen view appropriately.
• Updated unit tests to verify the fullscreen behavior.

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.

Steps to Reproduce

1. Open the modal by triggering the appropriate action.
2. Activate the fullscreen mode by setting the fullScreen property to true.
3. Observe that the modal expands to fill the screen.
