完全移除模块级权限系统，迁移至接口级权限

后端：
- 删除 StudyRolePermission 模型和 project_permissions API 文件
- 重写 project_permissions.py core，移除所有模块级权限函数
- 重写 permission_cache.py，移除模块级权限缓存逻辑
- 新增权限模板功能（PermissionTemplate 模型、API、服务层）
- 新增 permission_templates 数据库迁移
- 迁移 8 个模块（attachments、audit_logs、dashboard、faqs、
  faq_categories、fees_attachments、knowledge_notes、
  material_equipments、overview、subject_histories、subject_pds）
  至接口级权限检查
- 删除所有模块级权限相关测试文件，新增权限模板测试

前端：
- 删除 ProjectPermissions.vue 和 ProjectPermissionsModule.vue
- 重写 projectRoutePermissions.ts，改为基于接口级权限格式
- 更新 store/study.ts、router/index.ts、AuditLogs.vue、Projects.vue
  中的权限 API 调用，从 fetchProjectRolePermissions 改为
  fetchApiEndpointPermissions
- 清理 types/api.ts 中的旧模块级权限类型定义
- 新增 PermissionTemplateSelector.vue 组件
- 更新权限管理页面，移除模块级权限 tab
