[BUG] OS simulator panel: physical keyboard input is mapped as if the keyboard were ANSI/QWERTY

### What's Wrong?

Typing in the iOS simulator panel with a French AZERTY physical keyboard produces the characters of the US positions of the keys pressed

The panel appears to resolve each key by physical position against a US table, ignoring the host input source (com.apple.keylayout.French).

This is not an iOS-side setting. I set the simulator's hardware-keyboard layout to Automatic, then French, then US (defaults write -g AppleKeyboards … hw=…, device shut down and rebooted between each). Symptoms were strictly identical in all three cases.

Meanwhile the panel's own text injection is affected by that same setting: it sends US positions, so it types correctly with hw=US and is mangled with hw=French (KRAMP4T7 → KRQ?P'Tè). A setting that changes injected input but never physical input shows the two do not share a path — the remapping happens in the panel, upstream of the simulator.

Simulator.app was not running during any of these tests (verified with pgrep -x Simulator). Typing in a Simulator.app window is the standard Apple path and honours the layout; only the panel is affected.

### What Should Happen?

The panel honours the host input source, as Simulator.app does. Typing a produces a.

### Steps to Reproduce

Steps to reproduce
macOS host with a non-QWERTY physical keyboard (here: French AZERTY, com.apple.keylayout.French).
Open the iOS simulator panel and launch any app with a text field.
Tap the field and type a, 1, 0 on the physical keyboard.
Observe q, &, à.
Optional: change the simulator's hardware layout and reboot the device — no effect.

### Additional Information

_No response_

Start by tracing physical-keyboard handling in the iOS simulator panel and comparing it with the host input-source behavior described for Simulator.app. Reproduce on macOS with a French AZERTY keyboard, then verify that typing a, 1, and 0 produces the expected characters regardless of the simulator hardware-keyboard setting.
