The editor's mockup writes like the screens, and speaks its own language around them

- Numbers in the mockup follow what the app sends the screens (style, grouping from five digits, the space before
  %), a state without a unit stays as it is, and built-in cards carry the screens' names (Instellingen, not the
  editor's Einstellungen).
- Automatic in Language & region is labelled with what it means now (Home Assistant's language decides).
- A screen's status (Synced, Loading tiles, ...) shows in the editor's language; the screens keep reporting it in
  English, which the app reads.
- The doorbell example uses the alert examples of the editor's language; control labels keep their capitals.
- Editor bundle rebuilt with every language's texts.
