[Bug]: GestureButton cannot be assigned to CycleDpiPresets on MX Master 4

### 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?

Both

### OpenLogi version

0.6.23

### Operating system

Linux

### OS version & architecture

Linux Mint 22.3 (Ubuntu-based)

### Device model

MX Master 4

### How is the device connected?

Logi Bolt receiver

### Affected area(s)

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

### What happened?

I'm trying to use the large thumb GestureButton as a DPI toggle instead of the dedicated DPI button.

The documentation indicates that GestureButton is a valid binding target and CycleDpiPresets is a valid action.

However, assigning CycleDpiPresets to the GestureButton has no effect.

The dedicated DpiToggle button works correctly with the same action.

### Steps to reproduce

1. Connect a Logitech MX Master 4.
2. Install OpenLogi 0.6.23.
3. Configure two DPI presets.
4. Disable gestures:

gesture_owner = "Off"

5. Assign:

GestureButton = "CycleDpiPresets"

6. Save the configuration and restart the OpenLogi agent.

7. Press the GestureButton.

Expected behavior
Pressing the large thumb GestureButton should cycle through the configured DPI presets, just like the dedicated DpiToggle button.

Actual behaviour:
Nothing happens.
The DPI does not change.
The same action works correctly when assigned to DpiToggle.

Config:
schema_version = 3

[devices."receiver:98261b7cb5bd8f6b:slot:2"]
gesture_owner = "Off"
dpi_presets = [
1000,
200,
]
dpi = 200

[devices.2b042.bindings]
DpiToggle = "None"
GestureButton = "CycleDpiPresets"

Additional info:
Additional tests performed:

- DpiToggle = "CycleDpiPresets" works correctly.
- GestureButton = "CycleDpiPresets" has no effect.
- gesture_owner = "Back" together with Back = "CycleDpiPresets" also has no effect.
- The GUI currently does not offer assigning the DPI toggle action to the GestureButton.

Question:

Is this currently unsupported, or is this a bug?

If unsupported, would it be possible to allow the GestureButton to trigger CycleDpiPresets (or another DPI action)? This would provide functionality similar to the precision/sniper button available on Logitech G-series mice and would be very useful for productivity applications such as Lightroom, Photoshop and PowerPoint.

Open related request:
> **Would it be possible to support "hold for low DPI, release for normal DPI" on the GestureButton?**
> This would emulate the precision/sniper button found on Logitech G-series mice and would be very useful for productivity tasks such as photo editing and precise object placement.

### 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 by tracing how GestureButton, Back, and DpiToggle bindings are handled when they target CycleDpiPresets, using the configuration and logs in this report as the reproduction case. Compare the working DpiToggle path with the inactive GestureButton path, then verify that the configured gesture binding cycles the DPI presets while gestures are disabled.
