fix(desktop): console.log 清理 — 替换为结构化 logger

将 desktop/src 中 23 处 console.log 替换为 createLogger() 结构化日志:
- 生产构建自动静默 debug/info 级别
- 保留 console.error 用于关键错误可见性
- 新增 dompurify 依赖修复 XSS 防护引入缺失

涉及文件: App.tsx, offlineStore.ts, autonomy-manager.ts,
gateway-auth.ts, llm-service.ts, request-helper.ts,
security-index.ts, skill-discovery.ts, use-onboarding.ts 等 16 个文件
