Release v1.3.45

🔥 关键 bug 修复：
- 文件管理-管理员模式不能下载（缺 /api/admin/files/download 端点）
- 强制刷新页面后点链接无响应（Flask send_static_file 默认 12h 缓存，浏览器拿旧版 JS → onclick undefined）

✨ 增强：
- index.html 加 meta no-cache 标签（双保险）
- 管理员模式文件行加 ⬇️ 下载按钮
- downloadFile(name) 加 isAdminMode 分支

🧹 清理：
- file_manager.read_file max_size 1MB→50MB（与 main.py api_admin_files_read 一致）
