fix(optimize): 参数优化端到端修复(空statistics/500/不跳页)

根因: vnpy run_optimization 孙进程 spawn re-import setting.py 重置 DB → load 0根 → 空 statistics;连带 task_id 不一致 + statistics 含 date/numpy 序列化失败 + 前端单页轮询 180s 超时。
修复(不动 vnpy 源码):
- cta_optimizer: vt_setting.json 适配(vnpy 原生机制 setting.py:43 load_json,孙进程拿到正确 DB) + task_id 贯通 + 主聚合持久化(combos) + 过滤空 statistics 记录
- result_store: _json_default(date→isoformat + numpy→原生),save_result 两处 json.dumps 加 default
- routes: optimization-results 改读 DB 主聚合, fallback 内存(重启不丢)
- runner: _opt_worker 加 task_id 参数 + submit_optimize 传递(对齐 _cta_worker)
- 前端: Optimize 提交后跳 progress;Progress 用 opt_ 前缀判断跳 optimize-result;新建 OptimizeResult 参数表格页;router 加路由
验证: 端到端 optimization-results http=200 + 4组合非空 statistics + 浏览器提交→跳 optimize-result 页表格渲染。
