本体三支柱: 科目↔KPI↔OKR三层互联 + 追溯链API + OKR详情页签

- 新表 kpi_subject_map(89映射/24KPI) / objective_kpi(3O×5KPI) / krs(3O×3KR)
- GET /api/cma/ontology/trace?objective_id=N O→KPI→科目逐层追溯
- GET /api/cma/ontology/objectives 三层链路概览
- OkrDetail.vue 新增本体追溯链页签(KR目标/当前值 + KPI→科目标签流)
- 含并发已上线未提交的KPI多粒度列(target_monthly/quarterly/yearly)
- 回归: pytest 409 passed
