fix(industry): 二次审计修复 — 2 CRITICAL + 4 HIGH + 2 MEDIUM

C-1: Industries.tsx 创建弹窗缺少 id 字段 → 添加 id 输入框 + 自动生成
C-2: Accounts.tsx handleSave 无 try/catch → 包装 + handleClose 统一关闭
V1: viking_commands Mutex 跨 await → 先 clone Arc 再释放 Mutex
I1: intelligence_hooks 误导性"相关度" → 移除 access_count 伪分数
I2: pain point 摘要未 XML 转义 → xml_escape() 处理
S1: industry status 无枚举验证 → active/inactive 白名单
S2: create_industry id 无格式验证 → 正则 + 长度检查
H-3: Industries.tsx 编辑模态数据竞争 → data.id === industryId 守卫
H-4: Accounts.tsx useEffect 覆盖用户编辑 → editingId 守卫
