fix: remove dim step that leaks orphaned layer surfaces

dim creates a wlr-layer-shell surface that Hyprland never cleans up
when the process exits — leaves an opaque full-screen overlay (pid=-1)
covering the entire display until the layer tree is rebuilt.

Removing step 1 (dim) from hypridle prevents future occurrences.
unstick-display.sh now restarts waybar to force a layer tree rebuild
as a recovery measure.
