/**
 * AKSRT User Ban — 前台“禁封/解封用户”弹窗
 *
 * 1:1 复刻参考主题 Zibll 前台禁封能力：
 *   - zib_get_edit_user_ban_link      → [data-aksrt-ban] 委托入口（三点菜单内）
 *   - zib_get_set_user_ban_modal      → REST /user-ban/modal 拉取弹窗内容
 *   - zib_ajax_set_user_ban           → REST /user-ban/set 提交
 *   - zib_get_ban_info_modal          → [data-aksrt-ban-info]（查看禁封状态）
 *   - zib_get_user_ban_appeal_modal   → [data-aksrt-ban-appeal]（禁封申诉）
 *   - zib_get_ban_log_modal           → [data-aksrt-ban-log]（禁封记录）
 *   - zib_user_ban_appeal（wp-ajax）  → admin-ajax aksrt_ban_appeal_submit 提交
 *
 * 弹窗经 AksrtModalRuntime.openRemote 打开（与参考主题 refresh_modal 每次刷新
 * 同语义）：桌面 600px 宽（参考主题未传 data-class → Bootstrap .modal-dialog
 * 默认宽 600px）/ min-height 360px（data-height=360 → .modal-content 初始高度），
 * 移动端底部抽屉（mobileBottom）。提交成功语义与参考主题 zib_ajax_set_user_ban
 * 返回值一致：禁封 → reload:true（整页刷新），解封 → hide_modal:true（仅关闭弹窗）。
