feat(filelib): 项目级授权恒生效,移除独立权限开关(ADR-0030)

- permission.ts: effectiveRole 删除 D11 冻结分支,输入不再含开关字段
- treeService: 停止读 FileLibProjectSettings;建项目不再写默认行
- grantService/routes: 删 setIndependentPermission 与 PUT 路由;节点详情 DTO 去掉 independentPermission
- filelib-web: 概览 tab 移除开关;NodeDetail 类型同步
- 测试: 单测/集成改为断言恒生效语义;ADR-0030 废除契约 D11/P5
- FileLibProjectSettings 表保留(存量行忽略,不再读写),审计词表保留历史读取
