[ui] Reconstruction: Restore the Slot status of the clear method

[cbentejac]

Description

This PR fixes an issue introduced in cfd2b1e which changes the clear() method from the Reconstruction class from a slot to a regular method.

If clear() is not a slot, it cannot be called from the QML side. In practice, it made the "Home" button ineffective from the Application; once the Homepage had been left, it could not be returned to.

• Fixes the UI "Home" button functionality by ensuring clear() is callable via QML

• Ensure that the Slot decorator is correctly imported from the appropriate module (e.g., PySide2.QtCore or PyQt5.QtCore) to maintain consistency with the rest of the codebase.
