[Bug]: Smooth scrolling breaks scroll in some components on firefox

### 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

0.8.3

### Operating system

macOS

### OS version & architecture

26.6.2 (arm64)

### Device model

MX Master 3 (bluetooth) + PRO X Wireless (receiver)

### How is the device connected?

Bluetooth (direct, no receiver)

### Affected area(s)

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

### What happened?

On firefox, I loose the ability to scroll in some pages when I enable smooth scrolling. This happens with both my mice.

Example page: https://github.com/AprilNEA/OpenLogi/blob/master/Cargo.toml

If my cursor is specifically in the textarea, I am not able to scroll up/down. When I move it outside of the textarea I can scroll again.

Disabling the smooth scroll or shutting down OpenLogi makes the issue disapear. I was not able to reproduce on Google Chrome.

### Steps to reproduce

1. Open https://github.com/AprilNEA/OpenLogi/blob/master/Cargo.toml in firefox (I use **154.0.1 (aarch64)** for reference)
2. Move the cursor above the code in the textarea
3. Try scrolling => nothing happens
4. Move the cursor above the file strucure
5. Try scrolling => the page scrolls as expected

### 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 at the GUI smooth-scrolling and input-hook handling entry points, then reproduce the Firefox textarea case from the linked GitHub page with smooth scrolling enabled. Trace the behavior for both mice and verify that scrolling works over the code area without breaking the existing Chrome behavior.
