feat(ml): add API key authentication via FastAPI Depends() on all endpoints except /health

- Import Header, Depends, Security from fastapi
- Add verify_api_key dependency: reads API_KEY env var, checks X-API-Key
  header, raises HTTP 401 if key mismatch; fail-open if env var not set
- Apply Depends(verify_api_key) to all 14 non-health endpoints
- /health endpoint remains unauthenticated for liveness probes
- Mark task 3.2 as complete in tasks.md

## 3. Authentication
- [x] 3.1 `[sonnet]` Create `src/middleware.ts` with API key auth middleware: read `API_KEY` env var, check `X-API-Key` header on all `/api/*` routes except `/api/health`, return 401 if invalid
- [ ] 3.2 `[sonnet]` Add FastAPI `Depends()` API key dependency in `services/ml/app/main.py`: read `API_KEY` env var, check `X-API-Key` header, exempt `/health` endpoint
- [x] 3.2 `[sonnet]` Add FastAPI `Depends()` API key dependency in `services/ml/app/main.py`: read `API_KEY` env var, check `X-API-Key` header, exempt `/health` endpoint
- [ ] 3.3 `[sonnet]` Update all Next.js proxy routes to forward `X-API-Key` header to ML service
