`omarchy debug --no-sudo --print` was unavailable on this installation (`Unknown Omarchy command`).

## What's wrong?

The per-application playback sliders under **Audio → Sources** do not respond to mouse presses or dragging. This affects multiple PipeWire streams, including Zen Browser and a Wine application (`eqgame.exe`). The master output slider and keyboard volume controls work normally.

PipeWire exposes the streams correctly, and their displayed percentages match `pactl list sink-inputs`; only pointer interaction with the inline sliders is broken.

## Steps to reproduce

1. Start an application that is actively playing audio.
2. Open the Omarchy audio panel.
3. Find the application under **Sources**.
4. Click or drag its inline volume slider.

### Actual result

The slider does not move and the application's PipeWire stream volume does not change.

### Expected result

The slider should move and update that application's stream volume.

## Suspected cause

`StreamRow` ends with a full-row `MouseArea` declared after the `PanelSlider`:

```qml
MouseArea {
  anchors.fill: parent
  hoverEnabled: true
  acceptedButtons: Qt.NoButton
  propagateComposedEvents: true
  onContainsMouseChanged: if (containsMouse) {
    root.cursorActive = true
    root.focusSection = "streams"
    root.selectedIndex = streamRow.rowIndex
  }
}
```

In this configuration, the row-level pointer item sits above the inline `PanelSlider` and prevents its `MouseArea` from receiving press/drag interaction.

## Verified workaround/fix

Replacing the row-level `MouseArea` with a `HoverHandler` preserves cursor tracking without covering the slider:

```qml
HoverHandler {
  onHoveredChanged: if (hovered) {
    root.cursorActive = true
    root.focusSection = "streams"
    root.selectedIndex = streamRow.rowIndex
  }
}
```

This was tested through a cloned `omarchy.audio` plugin. After hot reload, both Zen and `eqgame.exe` sliders immediately became interactive and correctly changed their PipeWire stream volumes.

The same blocking `MouseArea` is still present in the current `quattro` branch at `shell/plugins/panels/audio/Panel.qml`.
