[Feature] Please add German keyboard to VM console

### The required feature described as a wish

As a User, Admin and Operator, I would like to use a German keyboard layout in the VM Remote Console. This helps prevent typing errors, especially when entering passwords.

The issue names only the VM Remote Console, with no file or test. Start by locating the console entry point and existing keyboard-layout handling, then check how console input is tested; done means the German layout can be used and produces correct characters, including during password entry.
