fix: 测试清单遗留bug批量修复(15条:商品库/消费/团队/设置/消息中心/平台套图/资产库)

- R6 商品图删除不生效: 封面asset移交+绕开prefetch缓存, 前端封面缩图补删除入口
- R48 消息中心长文本与UI框错位: 胶囊单行省略+优先级标签禁压缩
- R70 账单流水筛选: 后端加ledger_type过滤, count随筛选变化, 切筛选重置页码
- R72 月限额改后不刷新: 团队页/消费页自取最新teamSettings, 两页同源
- R83/R86 平台套图提示词框加大+模型胶囊嵌入输入框(复用Pill组件)
- R96 未读角标: 修KeyTextTransform注解过滤触发MySQL 3141致接口500
- R100 工作台记录丢失: 新增GET /api/ai/tasks/workbench/ 同源恢复, 废除localStorage方案
- R104 卖点添加按钮移出输入框, 新建抽屉+编辑态统一
- R106 商品库宽屏锁5列, 10个/页铺满两行
- R108 资产删除改软删+单张删除+回收站二次确认; trash页商品/资产双分区+restore/purge端点
- R109 生成图自动入资产库(person演员立绘除外), 迁移0008存量回填, 移除全部加入资产库入口
- R65 无需改动(22268d6已修, 测旧部署所致)

验证: tsc/build/check/makemigrations --check 通过, 后端测试210/210, perf-probe PASS
