feat(core): Wave 3 batch4 — 外壳账户菜单 + 设置dirty引擎 + 商品创建抽屉多图

全局外壳(sub-agent):侧栏 .user 点击弹账户菜单(头像+店名+用户名[非邮箱,认证定调]+
  个人设置/消息/团队/消费/退出),复用现成 .shell-account-menu CSS,点外部/ESC 收起
设置页(sub-agent):dirty-state 引擎(baseline+draft diff 13字段,顶栏「保存所有变更」
  无改动 disabled、改动激活+N项计数、统一保存、beforeunload、nav dirty-dot);修一处类型错(|| {} → 可选链)
商品创建抽屉(sub-agent):主图多图≤5+.pf-grid缩略网格+单张删、submit主图/卖点必填校验+收编bulletDraft、
  上传区拖拽变橙、卖点字重对齐;内联 style 抽进 css

验证: tsc 0 · build 0 · 走查 账户菜单5项+ESC、设置保存按钮无改动disabled、抽屉multiple+pf-grid 全过 · 0 console error

⚠️ 外壳:顶栏头像菜单接线需改 App.tsx/pipeline.tsx(超出单文件范围),侧栏入口已全可用。移交监督。
