[Bug]: G309 LIGHTSPEED buttons tab not showing

### Pre-flight checklist

- [x] I searched [existing issues](https://github.com/AprilNEA/OpenLogi/issues?q=is%3Aissue) and this is not a duplicate.
- [x] I am on the [latest release](https://github.com/AprilNEA/OpenLogi/releases/latest) or a recent `master` build.
- [x] I quit **Logi Options+** before running OpenLogi (the two apps fight over HID++ access and only one can own a receiver at a time).

### Which part of OpenLogi?

GUI (desktop app)

### OpenLogi version

0.7.10

### Operating system

Windows

### OS version & architecture

11 25H2

### Device model

G309 + LIGHTSPEED receiver

### How is the device connected?

Other / not sure

### Affected area(s)

- [ ] Device discovery / detection
- [x] Button remapping
- [ ] DPI control
- [ ] SmartShift
- [ ] Per-application profiles
- [ ] Battery status
- [ ] Settings / configuration (TOML)

### What happened?

The G309 buttons tab only shows on new installs and then when turning the mouse on it's gone and doesn't come back. Also the mouse doesn't show a picture in the UI.

### Diagnostics report

```markdown

```

### `openlogi list` output

```text

```

### Logs

```shell

```

### macOS permissions (if applicable)

- [ ] OpenLogi has **Accessibility** permission (needed to remap buttons via the event tap).
- [ ] OpenLogi has **Input Monitoring** permission (needed for Bluetooth-direct devices and capture).

Start with the OpenLogi GUI device view and the G309 capability and asset data reported by Diagnostics, then reproduce the issue using the three listed steps. Check why the G309 is reported with buttons=no and Render: none after the mouse is turned on. Done means the buttons tab remains available and the G309 image appears consistently.
