[Bug]: Copy/Paste doesn't work on alternate keyboard layout (Apple version)

### 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

0.6.18

### Operating system

macOS

### OS version & architecture

Tahoe 26.5.1

### Device model

MX Master 2s

### How is the device connected?

Bluetooth (direct, no receiver)

### Affected area(s)

- [ ] Device discovery / detection
- [x] Button remapping
- [ ] DPI control
- [ ] SmartShift
- [ ] Per-application profiles
- [ ] Battery status
- [x] Settings / configuration (TOML)
- [ ] Auto-update
- [ ] Menu bar / tray
- [ ] Other

### What happened?

I'm using a Mac with an AZERTY keyboard but a Workman layout. When I try to remap back and forward buttons on my mouse to do copy/paste actions, the copy does nothing and the paste close the current window.

### Steps to reproduce

1. Set keyboard in Workman
2. Assign Copy action to the back button
3. Assign Paste action to the forward button
4. Try to copy and paste

### Diagnostics report

### `openlogi list` output

### Logs

```shell

```

### macOS permissions (if applicable)

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

Start with the GUI button-remapping path and the event tap, then inspect how TOML settings represent Copy and Paste actions. Reproduce the Workman-on-AZERTY setup on macOS with an MX Master 2s; done means the back and forward buttons reliably copy and paste without closing the current window.
