feat(admin): Add user management and upgrade to module permission system

Browse Source 
Features - User Management (Phase 4.1):
- Database: Add user_modules table for fine-grained module permissions
- Database: Add 4 user permissions (view/create/edit/delete) to role_permissions
- Backend: UserService (780 lines) - CRUD with tenant isolation
- Backend: UserController + UserRoutes (648 lines) - 13 API endpoints
- Backend: Batch import users from Excel
- Frontend: UserListPage (412 lines) - list/filter/search/pagination
- Frontend: UserFormPage (341 lines) - create/edit with module config
- Frontend: UserDetailPage (393 lines) - details/tenant/module management
- Frontend: 3 modal components (592 lines) - import/assign/configure
- API: GET/POST/PUT/DELETE /api/admin/users/* endpoints

Architecture Upgrade - Module Permission System:
- Backend: Add getUserModules() method in auth.service
- Backend: Login API returns modules array in user object
- Frontend: AuthContext adds hasModule() method
- Frontend: Navigation filters modules based on user.modules
- Frontend: RouteGuard checks requiredModule instead of requiredVersion
- Frontend: Remove deprecated version-based permission system
- UX: Only show accessible modules in navigation (clean UI)
- UX: Smart redirect after login (avoid 403 for regular users)

Fixes:
- Fix UTF-8 encoding corruption in ~100 docs files
- Fix pageSize type conversion in userService (String to Number)
- Fix authUser undefined error in TopNavigation
- Fix login redirect logic with role-based access check
- Update Git commit guidelines v1.2 with UTF-8 safety rules

Database Changes:
- CREATE TABLE user_modules (user_id, tenant_id, module_code, is_enabled)
- ADD UNIQUE CONSTRAINT (user_id, tenant_id, module_code)
- INSERT 4 permissions + role assignments
- UPDATE PUBLIC tenant with 8 module subscriptions

Technical:
- Backend: 5 new files (~2400 lines)
- Frontend: 10 new files (~2500 lines)
- Docs: 1 development record + 2 status updates + 1 guideline update
- Total: ~4900 lines of code

Status: User management 100% complete, module permission system operational

**设计方案**：方案B - 合并对话框 + Tab切换
**核心原则**：
- ✅ **填补操作创建新列**（保留原始数据，便于对比）
- ✅ **新列紧邻原列**（方便用户查看和比较）
- ✅ **MICE功能必须实现**（医学研究核心需求）
- ✅ **无需撤销功能**（原始数据未被修改）

### 1. 数据安全 ✅ 已解决
- ✅ 填补操作创建新列，原始数据完全保留
- ✅ 新列紧邻原列，便于对比验证
- ✅ 无需撤销功能（原始数据未被修改）
- ✅ 用户可随时删除填补后的列，或重新填补
### 2. MICE性能 ⭐ 重点关注
- ⚠️ MICE在大数据集上可能很慢（10万行约1分钟）
- ✅ **必须显示进度条或加载动画**
- ✅ 添加"预计耗时"提示（基于数据量估算）
- ✅ 提供"取消执行"按钮（长时间任务）
- 💡 优化建议：考虑使用Web Worker或后台任务队列
### 3. 数据类型兼容性
- ⚠️ 均值/中位数只适用于数值列
- ✅ 需要前端验证列的数据类型
- ✅ 后端也需要校验并返回友好错误
### 4. 列名特殊字符
- ⚠️ 列名可能包含特殊字符
- <EFBFBD>?雿輻鍂<E8BCBB>唳<EFBFBD><E594B3>?`columnMapping` <EFBFBD>箏<EFBFBD>
- <EFBFBD>?蝖桐<E89D96>銝莜ompute<74>堒<EFBFBD><E5A092>賭<EFBFBD><E8B3AD>?
- ✅ 使用现有的 `columnMapping` 机制
- ✅ 确保与compute列功能一致
### 5. 全部缺失的列

**核心变更**：
1. ✅ **MICE功能必须实现**（医学研究核心需求）
2. ✅ **填补方式改为创建新列**（保留原始数据）
3. ✅ **新列位置：紧邻原列右侧**（便于对比验证）
4. ✅ **取消撤销功能**（原始数据未被修改，无需撤销）
**影响**：
- Python函数签名新增 `new_column_name` 参数
- UI新增"新列名"输入框
- 实现逻辑使用 `df.insert()` 确保位置正确
- 测试用例新增新列位置验证（TC-7, TC-8）
- 开发时间从3小时增加到5-6小时（MICE+新列逻辑）
**优势**：
- ✅ 原始数据完全保留，数据安全性更高
- ✅ 新旧数据并列显示，便于验证填补效果
- ✅ 用户可多次尝试不同填补方法对比
- ✅ 符合医学研究的严谨性要求
