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).

31 curated topics with 683 words (Fruit, Animals, Body, Eye, Sports,

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)

no account). Falls back to emoji for abstract words (40+ mapped).
Auto-enrichment: When a learning unit is created, images are
automatically fetched for all words that don't have one yet.

for existing words without images.
