feat(filelib): 老师端左栏导航:回收站 + 最近打开(ADR-0031)

- 回收站:listBin(祖先全活跃的已删顶点;管理员/直连 MANAGE 可见)、 restore(与 D15 对称只清本节点,落审计)、purge(仅管理员,pathIds 枚举子树按深度降序分批硬删,绕过 self-FK RESTRICT) - 最近打开:FileLibRecentVisit 表(filePath='' 兜底 PG 唯一索引),客户端成功打开后上报(VIEW 门禁,upsert 刷新),列表 20 条,D8/D15 可见性过滤 - 前端:/app 左栏(文件库/最近打开/回收站);RecentView/BinView; GridLibraryView 埋点 + navTarget 跳转(breadcrumb 建栈,role 已捎带) - 测试:filelib-nav 集成 4 例;全套 79 例绿
