### What happens

Several audio scripts parse `pactl`'s human-readable output with awk or
string matches. pactl is translated (gettext), so in a session whose locale
is, for example, `zh_TW.UTF-8`, `zh_CN.UTF-8` or `ko_KR.UTF-8`, the headers
and values the scripts look for are not there:

| Script | Parsed output | What breaks |
| --- | --- | --- |
| `omarchy-audio-output-set-default` | `pactl list sink-inputs` (`Sink Input #`) | Its stream-moving loop finds no streams (streams that follow the default sink still move through WirePlumber; streams with their own target stay) |
| `omarchy-audio-output-sink` | `pactl list sink-inputs` (`Sink Input #`, `Sink:`) | A DSP/tuning sink is not resolved to the physical sink, so volume goes to the wrong sink |
| `omarchy-audio-tuning` | `pactl list sink-inputs` in `app_streams` | Streams are not moved onto/off the tuning sink |
| `omarchy-audio-output-switch` | `pactl get-sink-mute` (`Mute: yes`), `get-sink-volume`, `-f json list sinks` (`availability`) | The OSD shows a muted output as unmuted |
| `omarchy-audio-output-volume` | `pactl get-sink-mute`, `get-sink-volume` | Mute state and OSD level are wrong |

To reproduce on any Omarchy install with an output device:

```sh
LC_ALL=zh_TW.UTF-8 pactl list sink-inputs | head -3  # translated headers
pactl set-sink-mute @DEFAULT_SINK@ 1
LC_ALL=ko_KR.UTF-8 pactl get-sink-mute @DEFAULT_SINK@  # not "Mute: yes"
```

(The locale must be generated; on Arch, uncomment it in `/etc/locale.gen`
and run `locale-gen`.)

### Fix

Against `quattro` at a15636b5 (2026-10-10).

Run only the parsed `pactl` calls in the C locale, as
`omarchy-audio-sink-availability` already does since #14431 (e1b0e5e9) and
as Omarchy does for `LC_ALL=C pacman -Qi`. The rest of each script, including the OSD text
and device descriptions, keeps the session's language.

`omarchy-audio-input-set-default` parses `pactl list short source-outputs`,
which is not translated, so it needs no change. `pactl list ... short`,
`get-default-sink` and the `move-*`/`set-*` commands print no translated
text that the scripts read.

### Verified

On Omarchy 4.0.4 (c668141e) with pipewire-pulse, in a VM whose session is
`zh_TW.UTF-8`, then `ko_KR.UTF-8`, with four output sinks:

- `omarchy-audio-sink-availability` (4.0.4): no output at all; with
  `LC_ALL=C`: all four sinks, each available. (The same fix as #14431.)
- `omarchy-audio-output-switch` (4.0.4): the default sink stays the same
  (the JSON filter drops every sink); patched: the default moves to the
  next sink and the playing stream follows it.
- `pactl get-sink-mute` on a muted sink prints `Mute: 是` / `Mute: 예`,
  so the 4.0.4 `== *yes` test reports it unmuted; with `LC_ALL=C` it
  reports it muted.
