安全加固 + 数据管线修复 + 质量改进(第2批)

安全加固: - /api/v1/predict 限流改用 get_client_ip 防 X-Forwarded-For 伪造 - 新增 TRUST_PROXY_HEADERS/REQUIRE_ADMIN_AUTH 配置,默认 fail-closed - 生产环境管理接口未配置鉴权时拒绝(503),不再放行数据管线修复: - injuries IntegrityError 改用 begin_nested(SAVEPOINT)隔离批次 - injuries 空名单 vs 未配置语义区分(has_data 精确标记) - bzzoiro 统计字段映射(shots/possession/cards) + 入库条件放宽 - available_at 语义收紧(回测防泄漏) - team_names NFKD 去变音双重查找 + 补齐变体键预测系统改进: - multi-agent 全专家失败时 status=degraded 跳过终裁 - agent_weights 独立持久化到 predictions 表新增迁移: - 0014_predictions_agent_weights.py 新增测试(8个文件): - test_ip_spoofing.py: 限流防伪造 - test_require_admin_fail_closed.py: 生产 fail-closed - test_injuries_integrity_rollback.py: SAVEPOINT 隔离 - test_injuries_slice_semantic.py: 空名单 vs 未配置 - test_available_at.py: 回测防泄漏 - test_bzzoirot_stats.py: 统计字段映射 - test_team_names_normalize.py: NFKD 变体 - test_multi_agent_degraded.py: 全失败 degraded - test_agent_weights_persist.py: 权重持久化
