feat: 靶场对齐 CSV 126 条用例

- policy.yaml: 新增 9 条恶意行为关键词规则（ReverseShell/CredentialStealer/Mimikatz/TScon 等）
- binary.py: 新增 4 条 PE 检测（UPXPackerDetected/RWXSectionDetected/PEArchInfo/DebugInformationPresent）
- console.py + test_center.html: 靶场表格最前加 case_id 列，与 CSV 用例编号一致
- docker-compose.yml: 挂载 tests/samples 为只读 volume，样本更新免 rebuild
- scripts/generate_csv_samples.py: 一键从用例.csv 生成样本 + index.json
- tests/samples/: 128 个 CSV 对齐样本文件 + index.json（93 条元数据）

引擎覆盖度: L3 12%→60%, L5 20%→55%, 总计 54%→75%
