feat: v0.11.0 素材库功能 + 生成页面 UI 优化

素材库（虚拟人像）：
- 后端：AssetGroup/Asset 模型 + 火山 Assets API 客户端 + 7 个 API 端点
- 前端：素材库管理弹窗（上传/浏览/追加/改名/状态轮询）
- PromptInput：@ 搜索素材库 + mention 标签（缩略图+名字）
- 提交生成时提取 asset:// 引用并去重
- 打开素材详情时自动检查云端状态，已删除的自动清理
- 后端 reference_snapshots 存储 thumb_url，刷新后标签缩略图和 hover 预览正常

生成页面 UI：
- 提示词 hover 即梦风格：原位展开玻璃底覆盖视频，不弹浮层
- 标签（AirDrama/时长/比例）inline 排列，溢出时 canvas 截断
- 详细信息弹窗支持鼠标移上去不消失（延迟关闭），增加 token/费用信息
- 任务卡片/视频详情页提示词标签化（renderPromptWithMentions）
- 视频详情页底部去掉重复按钮，信息栏 flex-wrap 自动换行

mention 标签：
- 输入框内剪切/复制粘贴保留标签（handlePaste 检测 text/html）
- 拖拽标签跟手（caretRangeFromPoint + drop 位置精确插入）
- 拖拽时 hover 预览自动关闭，InputBar 蓝边仅外部文件拖入时触发

其他：
- 联网搜索按钮（暂禁用，等火山确认 API）
- card max-width 800→1024，参考图缩略图 48→56px 居中对齐
- 导航箭头禁用时不触发关闭（去掉 pointer-events:none）
- API 错误信息附带原始报错便于排查
