新增: 灵感软删除回收站+雷达图正名(父⑤)

- IDEA-FIX-01: ideas 软删除(对标 tasks V14)— V28 迁移 deleted_at(幂等 ALTER) + IdeaRepo soft_delete/restore/list_deleted + list_by_query 恒带 deleted_at IS NULL(防回收站泄漏) + delete_idea 改软删 + restore_idea/list_deleted_ideas IPC + IdeaRecord 不加字段(纯 SQL WHERE 过滤)
- IDEA-FIX-14: 雷达图 CSS class radar→score-bar(IdeaDetail/ProjectDetail 2 文件 template+style+注释,纯正名零行为变更)
- 6 新测试(soft_delete 标记+过滤/幂等/missing, restore 还原/仅已删, list_deleted 排序);df-storage 73 测试过
