fix: 术语表上传/导入/导出全面修复+协同维护+离线保存

上传不触发问题:
- 原生file控件改为隐藏，由【导入CSV】按钮触发(triggerGlossaryImport)
- 折叠区和弹窗内都提供导入入口
- 导入后自动打开弹窗显示结果+提示导入条数

CSV解析鲁棒性:
- 用FileReader读UTF-8文本，Papa.parse(字符串)替代File对象，加手动parseCsvText兜底
- transformHeader剥离BOM+规范化，修复带BOM的CSV首列名变成zh导致中文列丢失
- normalizeGlossaryRow支持3列(zh/en/id)、2列任意组合、旧src/dst格式

协同维护+离线保存:
- loadGlossaryFromServer失败时从localStorage缓存回退
- saveGlossary先写localStorage再同步服务端，服务端失败提示"已保存到本机"
- openGlossaryModal用getOrCreateInstance复用实例避免重复创建

文案:
- glossaryHelp更新为三语说明+支持任意两列
- 新增glossaryImportBtn/glossaryImportNone/glossaryImportError/glossarySavedLocal
