Security hardening, async TeachChat, rate limit UX, unthrottle
...
Security:
- admin.py: move api_key from URL query params to POST body (litellm/models, tts/voices) — prevents key logging
- admin.py: sanitize exception messages in voice discovery — log internally, return generic errors
- teach.py: log LLM errors server-side, show friendly message to user
- nextcloud.py: normalize path with posixpath.normpath to prevent ../ traversal
- auth.py: check_rate_limit now accepts user param — admins/moderators/unthrottled always exempt
Performance:
- teach.py: make /chat endpoint async, use litellm.acompletion() — no longer blocks a uvicorn thread per request
Features:
- users: add is_unthrottled column (DB migration in setup_pgvector)
- admin.py: PUT /users/{id}/unthrottle endpoint
- AdminPage.jsx: Unlimited/Throttle toggle button per user, shows "unlimited" badge
- Rate limit messages improved with user-friendly context
