fix: display correct keys for international keyboards

Updates the ShortcutsModal to dynamically display the correct physical keys for users with non-US keyboard layouts.

The `ShortcutItem` component now uses `navigator.keyboard.getLayoutMap()` to resolve `KeyboardEvent.code` values (e.g., "Slash") to the character they produce on the user's active keyboard layout (e.g., "-").

This ensures the displayed shortcuts match the keys the user needs to press. A fallback is included for older browsers that do not support this API.
