feat(cms): 品牌叙事与结构性文案全站 CMS 化并补齐信任证据阶段 0

- 品牌叙事内核（价值主张/定位/承诺/三支柱/语气）下沉 site-config，经 SiteConfigProvider 注入全站
- 新增 page-copy 内容模型承载结构性文案（章节标题/眉标/描述/CTA/空状态），覆盖首页+服务/方案/产品/案例/新闻列表页，「CMS 优先 + 硬编码兜底」不白屏
- 首页「首批客户共创计划」板块（earlyAccessTitle/CtaLabel/Status 驱动）替代单行标签，如实呈现共创/内测/授权公开三档状态
- 关于页资质区数据空时如实展示「建设中」空态
- 零编造：不虚构客户/数据/资质
