Generate it / Publish it: Claude Haiku integration + Generate page redesign

- GenerateIt page: objects sidebar, readOnly canvas, collapsible prompt bar
- Generate it: calls Claude Haiku, saves questions/words to Directus as draft
- Publish it: promotes draft questions/words to published
- Deduplication: links existing words/questions instead of duplicating
- GenerateObjectsList: tree view with user_notes labels
- DrawCanvas: readOnly prop to disable mouse interaction
- api.ts: generateQuestions + publishQuestions endpoints
- requirements.txt: anthropic==0.40.0
