refactor: 统一价格入口 mo_data.get_price() - 22个脚本移除自拉腾讯API

所有价格获取统一走 mo_data.get_price() / get_prices_batch():
  - 优先读 live_prices(DB) → 无/过期才调 stock_quote(API) → 自动写回DB
  - 22个脚本全部替换：branch_scanner chip_factors divergence_detector
    market_screener mo_provider mofin_collect monitor_300308 300308_monitor
    multi_timeframe refresh_macro_context stale_detector stale_push_wlin
    stock_profile strategy_evaluator strategy_lifecycle strategy_review
    strategy-staleness-check technical_analysis xiaoguo_signal_consumer
