fix: 测试清单(7) 第7轮修复 — ZWQ/PMC/团队 8处真bug

- ZWQ-1 商品库: 编辑删图真生效 + 刷新后悬停垃圾桶图标恢复 (products.tsx/css)
- ZWQ-2 工作台: 最近项目进度条 5→4 段对齐视频项目, 完成态末段红→绿 (dashboard.tsx)
- PMC-4 消息中心: 收件箱文字错位修正 (messages-page.css)
- PMC-5 图片生成: 平台套图费用预估漏乘平台数, 改为 平台数×候选数×单价 对齐实扣(仅改展示, 不动扣费) (ai-tools.tsx)
- PMC-10 火山生图: 失败不再吞 response body, 错误体上抛便于定位 (volcano.py)
- PMC-11 团队: 创建账户弹窗禁止点遮罩误关 (overlays.tsx + team.tsx)

构建: npm run build EXIT=0 (1754 模块); volcano.py AST OK
注: PMC-10/YYX-8角标 等后端项需部署生效
