feat(KR): 行动挂KR完成 — action_plans.kr_id字段+API+前端目标/KR选择+KR中文名自动填+地图krs端点

- action_plans表加kr_id字段(关联krs.id)，create/update/list支持kr_id读写
- 创建行动选KR时自动继承objective_id；列表附kr_title
- 前端行动方案库加'所属目标/KR'两级联动选择，选中KR自动带出KPI
- OKR详情页KR卡片下显示达成行动列表(O→KR→行动三层)
- MapCanvasDialogs onKpiChange选中KPI自动填kr.name=kpi.kpi_name(中文)
- 编辑回填英文code KR名转中文显示兜底
- maps.py 新增GET /{map_id}/krs端点(MapReview战略回顾会KR进度)
- 数据修复: krs表9条英文code title→中文名(按kpi_definitions映射)
- 数据迁移: 高置信行动挂KR(费用率→kr10,应收→kr14); 地图32空KR清理
- okr list的kr_summary补metric_kpi_id(前端联动用)
- 新增6个kr_id测试(test_action_plans)，全量547通过
