feat: disk request body cache (#2780)

* feat: 引入通用 HTTP BodyStorage/DiskCache 缓存配置与管理

- 新增 common/body_storage.go 提供 HTTP 请求体存储抽象和文件缓存能力
- 增加 common/disk_cache_config.go 支持全局磁盘缓存配置
- main.go 挂载缓存初始化流程
- 新增和补充 controller/performance.go (及 unix/windows) 用于缓存性能监控接口
- middleware/body_cleanup.go 自动清理缓存文件
- router 挂载相关接口
- 前端 settings 页面新增性能监控设置 PerformanceSetting
- 优化缓存开关状态和模块热插拔能力
- 其他相关文件同步适配缓存扩展

* fix: 修复 BodyStorage 并发安全和错误处理问题

- 修复 diskStorage.Close() 竞态条件，先获取锁再执行 CAS
- 为 memoryStorage 添加互斥锁和 closed 状态检查
- 修复 CreateBodyStorageFromReader 在磁盘存储失败时的回退逻辑
- 添加缓存命中统计调用 (IncrementDiskCacheHits/IncrementMemoryCacheHits)
- 修复 gin.go 中 Seek 错误被忽略的问题
- 在 api-router 添加 BodyStorageCleanup 中间件
- 修复前端 formatBytes 对异常值的处理
