/**
 * 「前台投稿」后台设置页契约（对齐参考主题 1:1，不含专题）：
 * 1) PHP schema（SchemaPostList.php submit section）字段键、顺序、默认值与
 *    JS schema（assets/admin/src/schema/sections/post-list/submit.js）一致；
 * 2) 参考主题字段全集存在：post_article_s / post_article_btn_txte / post_article_cat /
 *    post_article_custom_filter_s / post_article_tag / post_article_user /
 *    post_article_title_strlen_limit / post_article_pay_free_s /
 *    post_article_pay_price_limit / post_article_pay_vip_price_s /
 *    post_article_pay_vip_1_discount / post_article_pay_vip_2_discount /
 *    post_t_placeholder / post_c_placeholder；
 * 3) 专题（topics）相关字段不存在；
 * 4) 旧 AKSRT 私有字段（front_submit_*、post_article_title_strlen_limit_min/max、
 *    post_article_pay_price_min/max）已彻底移除，无双路兼容；
 * 5) 运行时（PostDisplay::get_submit_settings）只读取新键。
