Vocab units created via /vocabulary/units only have QA items, no
pre-generated MC questions. Quiz now falls back to generating MC
questions client-side from QA items (EN word → 4 DE options).

All exercise pages now use useNativeLanguage() hook:
- Buttons show text in user's native language (Richtig→Dogru, etc.)
- Instructions translated (Geschafft→Bitti, Nochmal→Tekrar, etc.)
- wordInNative() available for vocab translations (needs data)
Pages updated: flashcards, quiz, type, listen, match, pronounce, story.

Next.js route-level layouts provide Sidebar + gradient background
automatically for all sub-pages. Individual pages no longer need
their own wrapper divs or Sidebar imports.
- learn/layout.tsx: Sidebar + purple gradient for all learning pages
- parent/layout.tsx: Same for all parent portal pages
- LearnLayout.tsx: Reusable component for other pages
- Fixed broken <LearnLayout>}> artifacts from previous refactoring
- Removed duplicate Sidebar/wrapper code from 9 sub-pages

HTTPS pages cannot fetch from HTTP backend ports. Added Next.js
API route proxies for /api/vocabulary, /api/learning-units, /api/progress
that forward to backend-lehrer internally (same Docker network, HTTP).
All frontend pages now use same-origin requests (getApiBase = '')
instead of direct port:8001 connections.
