## System

- Omarchy 4.0.3-mac.1
- Apple MacBook Air M2 (Asahi Linux, kernel 7.1.13-3-1-ARCH)
- Quickshell 0.3.0, UPower 1.91.4

## What happened

After charging to 100% and unplugging the charger, the bar's power widget keeps showing the charging icon / "Charging" label while the battery is actually discharging.

## Cause

The widget derives everything from the daemon-wide `UPower.onBattery` flag and never checks `displayDevice.state`. On this machine, the tps6598x USB-C PD port (`/sys/class/power_supply/tps6598x-source-psy-0-0038`) keeps reporting `online: 1` after unplug (stale source state; filed separately against Asahi Linux). UPower therefore sets `on-battery: no` even though its own battery device reports `state: discharging`:

```
upower -d  →  DisplayDevice: state: discharging ...  Daemon: on-battery: no
```

With `onBattery == false`, `Panel.qml` (`discharging` binding, lines 68–71) is false, so `Model.batteryIcon()` hits `if (!onBattery) return chargingIcons[index]` (`Model.js:77`) and `modeLabel()` falls through to "Charging" since percentage < 1 (`Model.js:89`).

## Expected

When `displayDevice.state === UPowerDeviceState.Discharging`, show the discharging icon / "On battery" regardless of the `onBattery` flag.

## Suggested fix

In `Model.js`, gate the charging icon on the device state, e.g.

```js
if (!onBattery && d.state === states.Charging) return chargingIcons[index]
```

and apply the same guard in `modeLabel()`. This also hardens the widget against driver-level inconsistencies of this kind (see also #10939, same trust-the-flag pattern).

## Steps to reproduce

Charge to 100%, unplug the charger. On Asahi machines with a stale `tps6598x-source-psy online=1`, the widget stays on "Charging" as the battery drains.
