fix(scripts): BackHall SpriteFrame UUID 修正到 atlas-hall 00191_01.png

之前脚本生成引用占位 UUID 8e3905be-...@f9941 (atlas-login 没这个 PNG)
现在用 atlas-hall 真实 spriteFrame UUID c9d95e2a-...@f9941 (00191_01.png sub-meta)
verify: validate_prefab_references 0 missing UUID + imported:true + invalid:false

第 4 项精灵资源图验证通过 (spriteFrame UUID 现在指向 atlas-hall/00191_01.png 真实资源)
