feat(service-manage): 服务管理功能升级 — 授权/目标/文档管理

- 新增服务授权模块：下载激活文件、上传授权文件、轮询任务状态
- 新增目标服务器管理：CRUD + 密码加密 + 连接测试
- 新增项目信息管理：保存/读取项目信息（销售/部署/密码/概述）
- 新增部署视图自检文档：模板下载 + 上传回传
- 前端 Authorization.vue 四步流程界面 + Targets.vue 目标管理页
- 后端 14 个 API 端点，管理员权限校验 + 审计日志
- 后端三层架构：routes/service_manage.py + services/service_manage.py + utils/paths.py
- 新增测试用例 test_service_manage.py
- 版本号分散配置（.env.example 新增 BACKEND/FRONTEND_VERSION）
- 服务监测增强：健康度趋势分析、通知服务、统计视图
- 问题排查优化：AI 服务支持自定义 model、离线模式 record_id
- 易用性优化：搜索面板组件、本地缓存、FAQ 面板优化
- PRD 文档：服务管理功能升级 + 易用性优化
