feat: DingTalk attendance import + integration config + expense types + UI polish

Server:
- Add DingTalk attendance import service with SSE progress streaming
- Add IntegrationConfig entity & module for multi-tenant DingTalk setup
- Add ExpenseType entity & ExpenseTypesModule
- Add SeedModule for DB initialization
- Add UserDingMapping entity for DingTalk user linkage
- Attendance service: import flow with dedup & student auto-mapping
- Rooms service: time-range overlap queries
- Sync controller/service: DingTalk integration wiring
- Permission guard: refactor to pure re-export
- Campus scope middleware: tenant-aware filtering

Admin UI:
- Attendance page: import UI with progress & result summary
- All pages: tableStyle/tablePagination standardization
- Login page: responsive styling
- Sensitive data: useViewSensitive hook for masked viewing
- Vite config: path aliases, build optimization
- Test infra: vitest config, test utilities
