### What happened
Renaming a paired Bluetooth device (via `bluetoothctl set-alias` or setting
the BlueZ `Alias` D-Bus property directly) does not change what the
Bluetooth bar panel displays. It keeps showing the device's original
hardware-advertised name.

### What was expected
The panel should show the custom alias, the same way GNOME/KDE Bluetooth
settings and `bluetoothctl devices` do — Alias is the whole point of a
user-facing rename.

### Root cause
In `shell/plugins/panels/bluetooth/Model.js`, `deviceLabel()` is:

    function deviceLabel(device) {
      if (!device) return ""
      return String(device.deviceName || device.name || "").trim()
    }

`device.name` is Quickshell's `Quickshell.Bluetooth.BluetoothDevice.name`
— writable (`setName`), backed by BlueZ's `Alias`. `device.deviceName` is
the read-only property backed by BlueZ's raw `Name`. The function checks
`deviceName` first, so any device with a real hardware name (i.e. every
device that has ever had a human-readable name) always shows that instead
of a custom alias, because `deviceName` is never empty.

### Suggested fix
Swap the priority:

    return String(device.name || device.deviceName || "").trim()

Verified locally: cloning the plugin and applying this one-line swap
makes the panel correctly reflect the alias.

### Steps to reproduce
1. Pair a Bluetooth device that has its own hardware name (e.g. headphones).
2. `bluetoothctl set-alias "My Custom Name"` (or set `Alias` via D-Bus).
3. Open the Bluetooth bar panel — the custom name never appears.
