feat(s1): 回测核心端到端跑通（vnpy client 对齐）

- 修 submit_cta/optimize 策略字符串→类解析（get_strategy_class）
- cta_engine: worker 进程设 vnpy DB→quant_trading.db（修 0 根数据）
- equity_curve 取自 calculate_result 的 daily_df（修 get_all_daily_results 对象问题）
- kline 补 cfg（find_config_path 共享）
- 端到端冒烟通过：DoubleMaStrategy 600000 → equity111/pnl111/trades1/kline117
