feat(admin): 新增后台文章列表销售数据列与快捷编辑配置项

「所有文章」列表此前只有互动数据列，缺少销售数据表头；快捷/批量编辑
展开后也只有原生三项。本次对照参考主题补齐这两处，不含专题链路。

- 新增 PostListEnhance：统管 sale/stats 两列、付费类型筛选、
  orderby=sales_volume 排序，以及四组快捷编辑字段的渲染与保存
- 新增 PostListEditFields：单独承载字段定义，主类职责保持单一
- 新增 admin-post-list.js：按 pay_type/pay_modo 勾选切换字段显隐
- 从 inc/core-hooks.php 迁出原有列实现（删 74 行），不再保留旧闭包
- 清理 admin-main.css 中确认无引用的 .aksrt-tab-pane 与 .aksrt-modal* 死块
- 新增 post-list-quick-edit-contract 测试，更新 stats/icon-picker 契约

快捷编辑锚点列用互动数据列而非参考主题的专题分类法列（本项目无专题）。
真实销量改为页面级批量查询，避免逐行查库。金额运算统一走 Ledger 的
「分」单位，不用裸浮点。保存走 edit_post 钩子，一次覆盖快捷与批量两条路径。
