Fix Error When Submitting Crop Tool Without Making a Selection

[foivospro]

Description

This pull request addresses the issue where an error occurs if the crop tool form is submitted without making a selection.

Changes Made

Added logic to set default values for x, y, width, and height inputs if no selection is made. This ensures the entire PDF is selected by default when the form is submitted without any user selection.

Closes #1342
