Anglicize tippen's codebase and finish pending UI/curriculum cleanup

- Rename all German identifiers, types, mode ids, file names, CSS classes
  and data-attributes to English throughout tippen/src; only user-facing
  text (lesson titles, word lists, labels, spoken praise) stays German.
- Add a word/nonsense-word list to the "Übung: die Grundstellung" home-row
  lesson in the curriculum.
- Remove the unused HandHint component and speech.ts, and carry forward
  the in-progress App.tsx/component/generator/progress edits from other
  sessions.
- Refresh the regenerated music-library cache index.
