feat(KR): KR完整修复 — krs表打通+方向符号operator+权重自由输入

- 后端okr.py: KR读取从ActionPlan改为krs表, 新增KR CRUD API(POST/PUT/DELETE /okr/{objective_id}/krs) + 批量sync
- operator方向符号: krs表加operator/tolerance/weight/sort_order/monthly_milestones列
- progress方向感知计算(>=/>: current/target, <=/<: target/current, =: 容差), 达成→status=achieved
- 关联KPI自动继承方向(threshold_green解析: F_COST_RATIO<=18等)
- maps.py: 保存地图时自动同步objectives+krs表, JSON→krs数据迁移脚本
- 前端: 权重下拉改自由数字输入(可小数33.33) + 方向选择器(≥/≤/>/</=) + 自动平分按钮 + KPI方向继承提示
- pytest: 10个新测试(krs CRUD/方向感知/权重校验/多租户隔离) + 更新旧KR测试
- 迁移: 现有strategic_maps JSON 12条KR已写入krs表
