主要功能： 1. ✅ 添加 canGenerate() - 检查登录、metered 订阅、余额 2. ✅ 添加 uploadBlobFiles() - 自动上传所有 blob URL 到服务器 3. ✅ 支付凭证强制验证 - identifier 缺失时报错"支付失败" 4. ✅ 新增 lib/api/upload.ts - 文件上传 API 5. ✅ 更新 useTemplateRun hook 支持 identifier 参数 完整流程（7步骤）： 1. 表单验证 2. canGenerate 检查（登录 + 订阅 + 余额） 3. 上传 blob 文件到服务器 4. recordTokenUsage 扣费并获取 identifier 5. 验证所有 URL 都是服务器 URL 6. 转换数据格式 7. runTemplate(id, data, identifier) 创建任务 安全保障： - ❌ 无 identifier → 抛出错误"支付凭证缺失" - ❌ blob URL 未上传 → 报错"存在未上传的文件" - ❌ 余额不足 → 引导用户充值 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
