i18n break the key shortcuts

## Description

In Chinese env, all shortcut can't work since the key map was broken.

I guess it's because the key map was sliced from the string.

e.g. EN [Pencil, Alt+P] become [铅笔, Alt+铅]. (Chinese keyboards are also QWERTY and no Chinese character can be pressed at once.)

### Steps to reproduce the bug

1. Switch to Chinese Language Pack.
2. See the tool list left.

## System

- Device: ASUS TUF Gaming A16 FA607PV_FA607PV
- OS: Linux Mint 22.1
- Desktop environment: Cinnamon 6.4.6
- Package format: (Mint predownloaded)
- App version: 1.0.2

Reproduce the issue by switching to the Chinese language pack and checking the tool list shortcuts. Trace how the shortcut key map is derived from translated labels, then verify that shortcuts work in Chinese as they do in English without breaking the displayed translations.
