Yaojia Wang 9ee3ec9b4e feat: add A-share and HK stock data via AKShare (TDD)
5 new endpoints under /api/v1/cn/:
- GET /cn/a-share/{symbol}/quote - A-share real-time quote
- GET /cn/a-share/{symbol}/historical - A-share historical OHLCV
- GET /cn/a-share/search?query= - search A-shares by name
- GET /cn/hk/{symbol}/quote - HK stock real-time quote
- GET /cn/hk/{symbol}/historical - HK stock historical OHLCV

Features:
- Chinese column names auto-mapped to English
- Symbol validation: A-share ^[036]\d{5}$, HK ^\d{5}$
- qfq (forward-adjusted) prices by default
- 79 new tests (51 service unit + 28 route integration)
- All 470 tests passing
