feat(settings): 设置与个人信息模块审计重构 — i18n + 服务注入解耦 + Error Boundary + 流式渲染

- 新增 SettingsService 接口 + Context 注入，组件层不再直接 import users/messaging actions

- 新增 resolveRoleSettingsConfig 配置驱动角色路由，删除 parent/student/teacher-settings-view 冗余文件

- 新增 SettingsSectionErrorBoundary，每个 TabsContent + profile 角色概览区块均包裹

- 新增 ProfileStudentOverview/ProfileTeacherOverview 异步 Server Component + 骨架屏，支持流式渲染

- 抽取 buildStudentOverviewData 等纯函数到 lib/student-overview-data.ts，便于单元测试

- 新增 settings.json 翻译文件（zh-CN + en），所有组件改用 useTranslations/getTranslations

- 重构 profile/page.tsx：i18n 适配 + Suspense 分区加载 + 业务逻辑抽离

- 同步更新架构图 004/005
