fix(dashboard): hide update action without permission

CHANGELOG.md

 ### 修复
 
+- 隐藏无应用更新权限用户头像菜单中的“检查更新”入口
 - 插件工具使用中文等非 ASCII 名称时 LLM 调用失败：主流 API 要求工具名匹配 `^[a-zA-Z0-9_-]{1,64}$`，现自动将非法名称转写为合法拼音名（`pypinyin` 缺失时退回下划线替换），冲突追加 `_2`/`_3` 后缀，并在工具描述前缀 `[原名: …]` 保留原名映射；`config_json.plugins` 配置键与插件内部仍使用原始名称，路由不受影响
 - 修复聊天页在"生成中"时于输入框持续打字导致消息列表上下轻微抖动的问题：输入框高度测量改为在离屏克隆节点上进行，不再瞬态改变页面布局
