feat(aia): Complete AIA V2.0 with universal streaming capabilities

Browse Source 
Major Changes:
- Add StreamingService with OpenAI Compatible format
- Upgrade Chat component V2 with Ant Design X integration
- Implement AIA module with 12 intelligent agents
- Update API routes to unified /api/v1 prefix
- Update system documentation

Backend (~1300 lines):
- common/streaming: OpenAI Compatible adapter
- modules/aia: 12 agents, conversation service, streaming integration
- Update route versions (RVW, PKB to v1)

Frontend (~3500 lines):
- modules/aia: AgentHub + ChatWorkspace (100% prototype restoration)
- shared/Chat: AIStreamChat, ThinkingBlock, useAIStream Hook
- Update API endpoints to v1

Documentation:
- AIA module status guide
- Universal capabilities catalog
- System overview updates
- All module documentation sync

Tested: Stream response verified, authentication working
Status: AIA V2.0 core completed (85%)

**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

**影响**：
- Tab 2新增2个填补选项（共6种方法）
- Python函数 `fillna_simple` 方法参数新增 `'ffill'` 和 `'bfill'`
- 测试用例从14个增加到18个
- 开发时间从5-6小时增加到6-7小时
**适用场景说明**：
- 均值/中位数：适合独立观察的数值变量
- 众数：适合分类变量
- 固定值：用户自定义场景
- **前向填充**：随访数据（如多次测量，用上次值填充）

**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
