fix(industry): 审计修复 — 4 CRITICAL + 5 HIGH 全部解决

C1: SaaS industry/service.rs SQL 注入风险 → 参数化查询 ($N 绑定)
C2: INDUSTRY_CONFIGS 死链 → Kernel 共享 Arc 接通 ButlerRouter
C3: IndustryListItem 缺 keywords_count → SQL 查询 + 类型补全
C4: set_account_industries 非事务性 → batch 验证 + 事务 DELETE+INSERT
H8: Accounts.tsx mutate 竞态 → mutateAsync 顺序等待
H9: XML 注入未转义 → xml_escape() 辅助函数
H10: update_industry 覆盖 source → 保留原始值
H11: 面包屑缺少 /industries → 添加行业配置映射
