### System details

Omarchy 4.0.4 on two machines (Dell XPS 14 with Intel Panther Lake, and a desktop with Ryzen 7 7700 / RX 9060 XT). PipeWire with pipewire-pulse, `pactl 17.0-98-gb096`.

### What's wrong?

When switching audio outputs with `omarchy-audio-output-switch` (Shift + Mute), the OSD shows `(null)` instead of the device name for any sink whose description contains non-ASCII characters. Switching itself works, only the name is wrong. I see it on both machines with a Bluetooth headphone named `🕺🏽Bose` and with a filter sink called `Calibrated Speakers — Protected` (em dash).

**Steps to reproduce**

1. Give a Bluetooth audio device a name with an emoji (or use any sink with a non-ASCII description) and connect it.
2. Press Shift + Mute until that output is selected.
3. The OSD shows `(null)`.

**Cause**

The script reads the name with:

```bash
next_sink_description=$(jq -r '.description // .properties."device.description" // .name' <<<"$next_sink")
```

`pactl -f json` can't escape non-ASCII. It prints `Invalid ASCII character: 0xffffffe2` to stderr and emits the literal string `"(null)"` for `description` and `device.description`. Since that's a real string, the `//` fallbacks never kick in.

This looks like a regression: #1695 and #2205 reported the same thing and #1859 fixed it with a `(null)` check, but that check went away when the script was rewritten in 1eab0cff ("Integrate swaybg and swayosd into the new shell"). Upstream PulseAudio fixed the JSON escaping (pulseaudio#1310), but it isn't in a tagged release yet (latest is still v17.0). As far as I can see, this script is the only place in Omarchy that reads names from `pactl -f json`; the audio panel shows the names correctly.

**Suggested fix**

Read the description from `pw-dump`, which keeps UTF-8 intact, and fall back to the sink name:

```bash
sink_description() {
  local d
  d=$(pw-dump 2>/dev/null | jq -r --arg n "$1" \
    'first(.[] | select(.type == "PipeWire:Interface:Node" and .info.props."node.name" == $n) | .info.props."node.description") // empty')
  [[ -n $d && $d != "(null)" ]] && { echo "$d"; return; }
  echo "$1"
}

next_sink_description=$(sink_description "$next_sink_name")
```

The smaller option would be to treat `"(null)"` as missing again, but then the OSD shows the raw `bluez_output...` name. I'm running the pw-dump version locally and it works on both machines.
