feat(ui): 导出/备份 — otpauth URI 列表 + 加密备份导出/恢复
- qr/export.go: EntryToOtpAuth + OtpAuth.URI，将 config.Entry 反向 转换为标准 otpauth:// URI（Battle.Net/Steam 标记为 partial） - dialog_export.go: Tab 切换对话框，otpauth URI 列表可复制 + 加密备份文件导出（独立密码，0o600 权限） - dialog_restore_backup.go: 从 .winauth.bak 恢复，密码验证后合并 - settings_menu: 新增 Export / Restore Backup 菜单项 - i18n: en/zh-CN/de 三语翻译
