feat: Phase 1 WinAuth Go 移植完整实现

将原 C#/.NET WinAuth 移植为 Go + Gio GUI，覆盖 Phase 1 全部功能。核心模块： - internal/authenticator: TOTP (Google/Microsoft/Okta) + HOTP + BattleNet + Steam，含 enroll/sync/code 生成、Steam 交易确认轮询 - internal/config: YAML 配置 + 老版 WinAuth XML 导入（DPAPI + Password + Blowfish/PBKDF2 解密链） - internal/crypto: 现代加密 (WAGO1) + DPAPI 跨平台封装 + 老版 Blowfish ECB - internal/win32: 单实例 Mutex 锁 + 全局热键管理器 (RegisterHotKey + PeekMessage 泵) + SendInput Unicode 注入 + 剪贴板文本/CF_DIB 图像读写 + AttachThreadInput 焦点切换 - internal/hotkey: "Ctrl+Alt+G" 风格快捷键字符串解析/格式化 - internal/qr: gozxing 二维码解码 + otpauth:// URI 解析 - internal/i18n: en/zh-CN/de 三语 TOML UI 模块 (Gio)： - 主窗口：圆环倒计时进度条、复制按钮 + Toast 反馈、空列表占位、行分隔线 - 添加流程：vendor 菜单 + 各 vendor 独立对话框 + 二维码扫描入口（文件 / 剪贴板） - 设置：密码加密、老版 XML 导入、每条目热键配置 - Steam：注册向导（含 captcha/email/SMS 多步）+ 交易确认窗构建：Windows 主目标，非 Windows 平台所有 Win32 功能走 build-tag 桩实现。
