版本管理全面增强：状态、补丁更新、热更新

1. 自动状态管理
   - 新增版本自动标记状态：最新版本为'有效'，旧版本自动标记为'已失效'
   - 前端列表页新增状态列和状态筛选

2. 更新方式升级
   - 更新方式从手动/自动改为：手动更新/热更新/完整更新
   - 热更新：运行时增量替换文件，无需重启
   - 完整更新：下载完整包替换，需重启

3. 补丁更新支持
   - 新增 base_version_id 字段支持增量补丁
   - 创建版本时可选择基础版本，自动识别为补丁模式
   - 补丁模式仅上传变更文件

4. ZIP解析上传（已有功能完善）
   - 上传ZIP自动解析文件列表
   - 支持选择入口文件

5. 国际化完善
   - 中英文新增状态、更新方式等翻译
