Fixing the next three scripts

-  `Tak0-Per-Window-Switch.sh` now records the listener PID in ``~/.cache/kb_layout_per_window.listener.pid``
    - reuses it if still running, preventing multiple background listeners
    - reports missing Hyprland sockets without exiting the main script.
-  `WaybarScripts.sh` adds a `launch_files()` helper that checks `$files` before execution;
    - if unset, it shows a notification instead of running an empty command.
-  `sddm_wallpaper.sh` validates `~/.config/rofi/wallust/colors-rofi.rasi` before use
    - extracts colors via a helper, and aborts with a notification if any required colors are missing.
