feat: HK realtime via Eastmoney push2 API — no more 15-min delay

price_monitor.py now splits A-share (Tencent realtime) and HK (Eastmoney realtime):
- fetch_all_prices() → A-shares only via qt.gtimg.cn
- fetch_hk_eastmoney() → HK stocks via push2.eastmoney.com (real-time, free)
- _fetch_hk_tencent_fallback() → fallback if Eastmoney fails (15-min delay)
- Eastmoney API: market code 116, fields f43(price)/f170(chg%)/f60(prev_close)
