feat: v0.8 平台扩展——3D渲染/打印中心/下料方案/设备/分享/验证码登录

- 3D展示: Three.js挤出重建窗型(玻璃半透明+型材盒体), 自研轨道控制
- 效果图渲染: Canvas场景合成(墙面/玻璃渐变高光/投影/三场景), 设置持久化
- 打印中心: A4生产订单模板(图纸+进度+签字栏), 打印CSS隔离
- 下料方案: 合同级汇总订单算料需求→FFD优化, 修正利用率为已排入/已用料
- 设备模块: 序列号+激活码绑定, 防重复绑定
- 订单分享: HMAC可逆token + 免登录公开只读页(customOrder-share)
- 验证码登录: mock短信通道全流程可用(发码/校验/自动注册), 接签名后换provider
- 帮助文章接口; 新增支付单适配层(微信/支付宝凭据就绪即接通)
- 前端新增6页面, 共18页面
