test: Update tests to use event.code format for keyboard shortcuts

- Update keybinding tests to use event.code instead of event.key
- Add forwarding test for keybinding service
- Align tests with the fix for non-English keyboard layouts

This ensures tests match the application's use of event.code for
language-independent keyboard shortcut handling.
