gahusb	bb03cc4525	perf(signal_v2): raise stock_client TTL for NAS load relief (SP-A1) ... portfolio 60s → 180s (3분 폴링 → 3회당 1회 fetch) news-sent 300s → 600s (sentiment는 자주 안 바뀜) screener 60s → 300s (Top-20 분 단위 변화 미미) V2 재시작 시점부터 NAS stock에 대한 인바운드 호출이 분당 12 → 분당 3~4 로 감소 예상. 캐시 hit ratio 0~50% → 66~80%. 회귀 테스트 3건 추가로 미래 의도치 않은 TTL 변경 차단. Also update test_stock_client.py fake_time assertions from 61.0 → 181.0 to match the new 180s portfolio TTL (tests were TTL-dependent).

gahusb	8469bf7ffa	feat(signal_v2): stock_client + 6 integration tests ... httpx async client with custom retry loop (max 3, exponential 1s/2s/4s), memory dict cache (portfolio 60s / news-sentiment 300s / screener 60s), X-WebAI-Key auth header injection. Stale fallback returns last successful response with logger.warning on persistent failures. 6 integration tests pass with respx httpx mock.
