Schema 收口第六轮：继续补 page_display / payment / post-list 依赖尾项

继续 Workstream C，清理剩余的 PHP schema dependsOn 尾项：

- payment.gateway：继续为 xunhupay / xhpay / payjs / epay / stripe 补齐 provider 开关下的
  PHP dependsOn，使网关配置折叠逻辑不再只停留在前端 schema。
- post_list.thumb / filter：补齐随机封面、多图模式、视频静音、首图尺寸、AJAX 筛选维度、
  自定义筛选与按分类绑定筛选的 PHP dependsOn，收回“总开关 -> 子配置”节奏。
- page_display：继续为 header-components 的搜索/图标卡片分支与 category 头图补 PHP dependsOn，
  让 page_display 在 PHP 层也具备与前端一致的展开契约。

验证：
- php -l 通过：page-display / payment / post-list 三个 PHP schema 文件
- node --check 复核通过：payment/gateway.js、post-list/filter.js、post-list/thumb.js、page-display/index.js
