feat(settings): 合并内外两个'关于' + 一键导出错误日志

[appergb]

User description

用户反馈

1. 设置内外两个"关于"重复：设置侧栏有 "关于" tab，弹窗（菜单栏 → 设置）也有 "关于"，体验割裂
2. 需要一键导出错误日志：跨 macOS / Windows，让用户选保存位置，便于反馈排查

T2 合并"关于"

• 删 `Settings.tsx` 的 `'about'` tab（enum + SECTION_ORDER + 渲染分支 + AboutSection 函数）
• `SettingsModal.tsx` 的 `AboutMini` 接管所有内容：
  • source GitHub 链接 ✅
  • QQ 群行（1078960553 + 复制按钮）✅ 保留所有数据
  • docs / feedback / privacy / localFirst / 检查更新（已有）

T3 一键导出错误日志

层	改动
Cargo + npm	引入 `tauri-plugin-dialog`
Backend `lib.rs`	plugin init + `log_dir_path` 改 `pub fn`
Backend `commands.rs`	`export_error_log(target_path: String) -> Result<(), String>` 用 `std::fs::copy`
Frontend `ipc.ts`	`exportErrorLog` wrapper：plugin-dialog `save` 选路径 → invoke 后端
Frontend `AboutMini`	新增"导出错误日志"行 + busy/ok/err 状态 + tooltip 显示实际路径

跨平台支持：log 路径 mac `~/Library/Logs/OpenLess/openless.log`、windows `%LOCALAPPDATA%\OpenLess\Logs\openless.log`，前端调用一致。

5 locale 同步翻译（10 个新 key）

`source / qq / qqDesc / copyQq / exportErrorLog / exportErrorLogDesc / exportErrorLogBtn / exporting / exportSuccess / exportFailed` 同时加到 zh-CN / en / zh-TW / ja / ko，保证 `typeof zhCN` 类型完整不破坏编译。

验证

• `npx tsc --noEmit` 通过
• `vite build` 通过
• `cargo check` 通过（plugin-dialog 与 tauri ~2.10 兼容）
• PR CI `Windows Tauri checks` + `pr_agent_job`
• 本地 build 后真机点"导出错误日志"测 dialog 弹出 + 文件落盘

解耦说明

保留 `settings.about.*` i18n 块（即使 UI 不再用），避免破坏其他可能引用；下个清理 PR 再统一删。

⚡ Recommended focus areas for review Stale Timeout The success path starts a 4-second timer that resets exportStatus, but that timer is never cleared on unmount. If the user exports a log and closes the modal before the timer fires, React will update state on an unmounted component, which can produce warnings and leave a dangling timeout. const onExportLog = async () => { setExportStatus('busy'); setExportMessage(''); try { const ts = new Date().toISOString().replace(/[:.]/g, '-').slice(0, 19); const target = await exportErrorLog(`openless-${ts}.log`); if (target == null) { setExportStatus('idle'); return; } setExportStatus('ok'); setExportMessage(target); window.setTimeout(() => setExportStatus('idle'), 4000); } catch (err) {
