Pull Request Overview

This PR aims to update the layout switching mechanism by removing dependency on XApp and instead using Cinnamon’s dbus interface for managing keyboard layouts. Key changes include removing XAppKbdLayoutController usage, refactoring layout switching logic in the screensaver password entry, and implementing a new CinnamonClient to interact with Cinnamon’s input sources.
