perf(deploy): force the unused audio stack off

Prev Next 
The block enabling pipewire was commented "for transaction sounds", but
no such sounds exist: nothing under apps/machine or packages/ constructs
an Audio element or ships an audio file. It has been dead weight for as
long as it has been there.

Removing our own `enable = true` is not enough. services.xserver pulls
in NixOS's graphical-desktop module, which mkDefault-enables pipewire
exactly as it does speechd, so the stack survived the first attempt at
this. That is why the line sits beside the speechd mkForce rather than
where the old block was.

Most of PipeWire's dependency chain is shared with the GStreamer that
Electron drags in, and that stays in the closure either way, so this
frees 21MB rather than the whole stack. The remainder comes out with
gtk4/gst, which wants a launch test on the sintra first.
