API integration tests for FastAPI endpoints (INTG-01).

Tests cover:
- Agent endpoints (list, create, update, delete)
- Canvas endpoints (present, submit, close)
- Episode endpoints (create, retrieve, search)
- User endpoints (profile, settings)
- Request/response validation
- Error handling (401, 403, 404, 422)
