Mouse cursor and crosshair both move simultaneously when using a connected mouse on iPad

Title:
Mouse cursor and crosshair move simultaneously when using a mouse on iPad

Issue:
When a mouse is connected to an iPad, both the system mouse cursor and the in-game crosshair respond to movement at the same time, causing conflicting input and visual interference.

Description:
On iPad devices with a connected mouse (via Bluetooth or USB), moving the mouse causes both the native iPadOS cursor and the game's crosshair/aiming reticle to move concurrently. This results in two on-screen pointers overlapping or drifting apart, making precise aiming and menu navigation difficult. The expected behavior is that the mouse input should control either the crosshair (in gameplay) or the system cursor (in menus), but not both simultaneously.

Steps to Reproduce:

1. Connect a mouse to an iPad via Bluetooth or USB-C.

2. Launch the game and enter any world or menu screen.

3. Move the mouse physically across the surface.

4. Observe both the iPadOS white cursor circle and the in-game crosshair's position.

Observed Results:
Both the system mouse cursor and the in-game crosshair move together when the mouse is moved, creating duplicate pointers that interfere with each other.

Expected Results:
Only one pointer should respond to mouse movement at a time — either the system cursor during menu navigation, or the crosshair during gameplay, but not both simultaneously. The mouse input should be properly captured by the game without the iPadOS cursor overlaying the screen.
