feat(kyc): 实现实名认证和更换手机号功能

主要变更:
- 注册流程: 添加跳过短信验证选项(3分钟后显示)
- KYC功能: 手机号验证 + 身份证实名认证(阿里云二要素)
- 更换手机号: 四步验证流程(旧手机验证→输入新号→新手机验证→确认)
- 独立管控: phoneVerified, emailVerified, kycStatus 三个状态分别管理

后端:
- 新增 KYC 控制器和服务
- 新增更换手机号 API 端点
- Schema 添加 KYC 和验证状态字段
- 集成阿里云身份二要素验证

前端:
- 新增 KYC 入口页、手机验证页、身份证验证页
- 新增更换手机号页面
- Profile 页面添加实名认证入口
