Fixing more scripts for Hyprland-Dots

  - `WallustSwww.sh` now reads the focused monitor’s cache file (or parses swww query per-monitor) to pick the correct wallpaper path
    - Eliminating the previous “last line wins” bug on multi-monitor setups.
  - `PortalHyprland.sh` suppresses harmless killall errors and launches only the first available portal binary in each category (hyprland + general)
    - Avoiding duplicate processes when both `/usr/lib` and `/usr/libexec` variants exist.
  - `KillActiveProcess.sh` checks that Hyprland returned a numeric PID before calling kill
    - Notifies the user when no active window is available instead of throwing kill usage errors.
