Update and revert image path in settings dialog

Capture the original state.image_path at dialog start, connect the Image Path QLineEdit's textChanged signal to update state.image_path immediately, and restore the original image_path if the settings dialog is cancelled. This matches existing undo behavior for width/offset/opacity and prevents partial image path edits from persisting when the dialog is rejected.
