Two buttons on topic cards:
- "Anzeigen": Shows words in search results (for review)
- "Alle zur Unit": Adds all topic words to the unit builder directly
Both buttons load from Kaikki and respect selected language.

Topics API now accepts lang= parameter. When lang=de, the word
labels are translated from English via Kaikki translations:
"eye, pupil, iris" → "Auge, Pupille, Iris"
Frontend sends searchLang to /topics endpoint and displays
display_words (translated) instead of words (English).

When user selects DE and types "Auge", the topic "Eye/Auge" is found
correctly. But "Alle laden" must search words with lang=en because
the topic word list is English (eye, pupil, iris...).

31 curated topics with 683 words (Fruit, Animals, Body, Eye, Sports,
School, Family, Weather, etc.). When user types a word that belongs
to a topic, the topic appears as a suggestion with "Alle laden" button.
Clicking "Alle laden" fetches all words from that topic via Kaikki
and displays them for easy selection into a learning unit.
New endpoint: GET /api/vocabulary/topics?q=banana
New table: vocabulary_topics (topic, words[], word_count)

Search now sends lang= to API (was always defaulting to EN).
Users can select any of the 24 languages in the search bar dropdown.
Placeholder text changes based on selected language.

Search endpoint now defaults to source=kaikki, searching the
vocabulary_kaikki table with 6.27M Wiktionary entries.
/filters returns kaikki_total and kaikki_languages count.
/vocabulary header shows "6,271,749 Woerter in 24 Sprachen".
Manual vocabulary_words (27 entries) still accessible via source=manual.

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.

Strategic pivot: Studio-v2 becomes a language learning platform.
Compliance guardrail added to CLAUDE.md — no scan/OCR of third-party
content in customer frontend. Upload of OWN materials remains allowed.
Phase 1.1 — vocabulary_db.py: PostgreSQL model for 160k+ words
with english, german, IPA, syllables, examples, images, audio,
difficulty, tags, translations (multilingual). Trigram search index.
Phase 1.2 — vocabulary_api.py: Search, browse, filters, bulk import,
learning unit creation from word selection. Creates QA items with
enhanced fields (IPA, syllables, image, audio) for flashcards.
Phase 1.3 — /vocabulary page: Search bar with POS/difficulty filters,
word cards with audio buttons, unit builder sidebar. Teacher selects
words → creates learning unit → redirects to flashcards.
Sidebar: Added "Woerterbuch" (/vocabulary) and "Lernmodule" (/learn).
