docs: log power-profile Waybar parity as a follow-up

The custom/powerprofile indicator is missing from the whole-swap summer
themes (its exec uses Nix-built script paths that can't go in static
JSON). Note the fix (promote the scripts to named bins on PATH) and the
general "new module → also add to whole-swap themes" rule.
