feat: RAG inline citations, source highlighting, and admin panel

- Increase RAG retrieval from 5 to 50 docs with relevance threshold (0.15)
- LLM inline citations with [来源N] format and reference list
- Clickable citation links scroll to source cards with highlight animation
- Source previews with full chunk text and answer-matched highlighting
- Message-scoped source IDs to fix cross-round citation targeting
- Admin panel pages (knowledge, users, forum, course, settings)
- Add rehype-raw dependency for HTML-in-markdown rendering
