第57批续21-fix: 修子领地创建不落库+确认创建按钮显隐

修1(问题2根因): saveAreaToDb INSERT VALUES 占位符76->77。续21加parent_id列(第77列)
但VALUES漏加第77个?,JDBC setInt(77,..)越界→SQLException被catch吞掉→DB未写入
→但代码继续areas.put+提示成功→loadAllAreas清空内存重读DB→子领地消失→传送/cli菜单找不到。
补全77个占位符后DB正常写入,loadAllAreas后子领地保留,传送/cli菜单可见。

修2(问题1): 圈地棒选区智能识别按钮显隐——身份不合格或部分重叠时不展示确认创建按钮。
canCreateSub标志:身份不合格→false,部分重叠→false,合格→true;false时隐藏一键创建链接,
提示'因身份或范围限制,已隐藏确认创建按钮'。confirm_create命令层闸门不变(双保险)。
