[Bug]: Inconsistent Keyboard Shortcut Behavior on Non-QWERTY Layouts

### Verified issue does not already exist?

- [x] I have searched and found no existing issue

### What happened?

When using non-QWERTY keyboard layouts (e.g., Dvorak), application keyboard shortcuts behave inconsistently. Some shortcuts respect the OS-assigned logical key mapping, while others appear to be hard-coded to physical key positions.

### How can we reproduce the issue?

Switch system keyboard layout to Dvorak (or any non-QWERTY layout).

Open the application and attempt to use common shortcuts:

Ctrl+Z → Undo works correctly, respecting the OS-assigned key mapping (logical "Z").

Delete → Requires pressing the physical "D" key on the keyboard, rather than the logical "D" key in the layout ("H" in Dvorak).
